PolicyIQ · Passenger Airlines L2

▶ How to read this dashboard click to expand — six channels, bidirectional scoring, weighted signals

PolicyIQ tracks the policy environment facing each industry as a structured signal stream. For passenger airlines, fourteen active signals operate across all six policy channels and create measurably different exposure across the twelve covered carriers. The headline finding is dispersion of 5.0×: the most policy-exposed carrier in our coverage faces five times the headwinds of the least exposed. Sector exposure (681) dwarfs sector tailwinds (84) by roughly eight to one, which means the policy environment is overwhelmingly negative for the industry as a whole — but the differentiation across firms still creates meaningful relative-value structure.

The six policy channels

Kinetic & geopolitical · active conflict, route disruption, oil shock. Trade & market access · tariffs, frequency caps, bilateral trade deals. Sanctions & export controls · entity lists, overflight bans, technology licenses. Fiscal & industrial policy · tax credits, mandates, ETS pricing. Competition & sectoral regulation · antitrust, consumer protection, labor rules, slot allocation. Institutional & political risk · enforcement intensity, agency capacity, executive intervention.

Bidirectional signal scoring

Each signal is scored separately as negative exposure (0–5) and positive tailwind (0–5) for each firm. A signal can hurt one firm and help another — Boeing delivery risk hurts Boeing-heavy operators but is a tailwind for Airbus-heavier carriers; slot allocation rules hurt expansion-stage ULCCs but are a tailwind for slot-rich legacies. Bidirectional scoring distinguishes "insulated" firms from "true beneficiaries", which a single-score system would conflate.

Signal weighting

Each signal carries a magnitude weight reflecting its peak impact on the sector: 1× moderate, 2× significant, 3× highest impact. Weights are applied at the signal level, not the firm level — a firm's score on a 3× signal counts three times as much in the channel rollup as the same score on a 1× signal. This prevents the framework from conflating five small signals with one massive signal.

Reading the dashboard

The dashboard moves from structural picture to firm-level detail to action: Porter shows how the signals collectively shift industry forces; the firm attribute matrix shows the underlying exposures that drive scoring; the channel rollup aggregates negative and positive scores into the headline ranking; the industry structure section addresses M&A as a meta-policy variable; synthesis identifies the four firm clusters and what to do with each.

Active signal inventory 14 signals · 6 channels

Fourteen active signals across all six channels. Magnitude weights reflect the peak impact of each signal on the sector: 1× moderate, 2× significant, 3× highest impact. The weights are applied at the signal level so that the channel rollup further down properly reflects which signals are doing the most work. Five signals carry the highest weight — together they account for the dominant share of the sector's exposure score.

Aggregate Porter view enhanced · signal-to-force matrix

The aggregate Porter view sits early in this L2 build deliberately — Porter is the most familiar analytical framework in the document, and using it as the structural orientation lets the reader anchor in known territory before absorbing the firm-level detail that follows. The view shows how the fourteen signals collectively shift the five forces for passenger airlines. Two views are presented together: per-force cards summarize the directional shift and the structural mechanism; the signal-to-force matrix below maps each individual signal to its impact on each force, letting a corporate strategist locate which policy triggers most threaten which force and letting an investor see which forces are being moved by which signals. The matrix is a new L2 object — the cards alone narrate change but the matrix makes the attribution explicit and contestable. The firm-level implications of the per-force shifts (which companies gain, which lose) are pushed down into the synthesis section so the Porter view stays focused on the structural picture.

↑ Force 1 of 5

Buyer power

Increasing materially. DOT consumer protection rules effectively give passengers contractual rights they previously lacked; the CFPB/DOT loyalty inquiry threatens the largest source of buyer-side capture (frequent flyer programs) by attacking the disclosure and devaluation mechanics that bind customers to single carriers. Net effect: passengers gain leverage on both the cash and the loyalty side.

Drivers: DOT consumer rules, CFPB/DOT loyalty, slot rules

↑ Force 2 of 5

Supplier power

Increasing significantly. Boeing's production caps under FAA oversight have effectively given Boeing pricing power on remaining deliveries despite reputational damage; engine maker concentration (CFM, P&W, RR) means engine OEMs dictate maintenance timelines; pilot unions have extracted historic contract gains; SAF producers are scarce relative to mandate demand. Almost every supplier category has gained leverage in the past 24 months.

Drivers: Boeing/FAA, pilot rules, SAF supply, ATC staffing

↔ Force 3 of 5

Threat of new entrants

Decreasing if anything. Slot constraints at major airports + tightened use-it-or-lose-it rules + capital requirements for fleet acquisition + regulatory compliance load all raise the barrier to entry. The JetBlue/Spirit merger block (now historical) was one of the few signals that could have lowered the bar; that path is closed. Net effect: structural advantage to incumbents, especially slot-rich legacies.

Drivers: slot rules, FAA enforcement, fleet supply

↔ Force 4 of 5

Substitute threat

Roughly unchanged from these signals alone. Aviation faces substitute threat mostly from rail (in EU intra-bloc) and from videoconferencing (on business travel), neither of which is materially affected by current signals. The tangential effect is that rising airline cost stack from SAF/ETS makes rail relatively more competitive in EU short-haul, which is a slight headwind for intra-EU LCCs.

Drivers: ETS/SAF (indirect via cost stack)

↑ Force 5 of 5

Internal rivalry

Increasing on differentiated firm exposure. Because the six active channels create such different exposure profiles across airlines, competitive dynamics are now firm-specific rather than category-wide. Domestic operators with US production fleets gain relative position vs. Pacific-exposed legacies; legacies with strong loyalty franchises gain vs. ULCCs but face concentrated CFPB risk. The competitive landscape is reshuffling on policy axes that didn't exist five years ago.

Drivers: cross-channel attribute heterogeneity

Signal × Porter force attribution matrix new L2 object

For each of the fourteen active signals, this matrix shows the strength of impact on each of the five Porter forces. Read row-wise for an investor view: "this signal moves which forces?" identifies the propagation pathways for each policy event. Read column-wise for a corporate-strategy view: "which signals threaten this force?" lets a strategy team locate the policy triggers they need to monitor for any specific competitive dynamic. This is the framework's first attempt to make Porter attribution explicit and contestable rather than narrative.

Reading the matrix · column patterns: Buyer power moves on just two signals (CFPB/DOT loyalty inquiry, DOT consumer rules) but both are strong — the regulatory channel is doing essentially all the buyer-power work. Supplier power moves on six signals from four different channels — this is the most diversified force in terms of policy attribution and the hardest to "fix" because no single signal change unlocks supplier power restoration. New entrant barriers move primarily on slot allocation rules with secondary effects from frequency caps and pilot supply — the regulatory channel is doing the work here too. Substitute threat is barely moved by any signal except weakly via the EU cost stack. Internal rivalry is the most-impacted force overall — twelve of fourteen signals affect rivalry meaningfully, which is consistent with the framework's claim that policy is now actively reshaping the competitive map within the sector.

Reading the matrix · row patterns: Russia overflight is a textbook single-channel signal that primarily moves rivalry (its core effect is competitive distortion) without touching buyer power or substitutes — making it conceptually clean to model. The CFPB/DOT loyalty inquiry is the matrix's most concentrated signal: strong on buyer power and rivalry, near-zero everywhere else — which is why the framework flags it as the highest-impact under-priced single signal for US legacies. Boeing delivery risk has the framework's strongest single-cell impact on supplier power because it directly determines pricing leverage in the OEM relationship. SAF mandates and EU ETS are the only signals that meaningfully move substitute threat, via the cost stack pushing intra-EU passengers toward rail. The matrix exposes which signals are doing distinct vs. redundant work: signals that have similar row patterns are doing similar Porter work and can be analyzed jointly; signals with distinct row patterns are independent and need to be tracked separately.

Methodology & limits: impact intensities are subjective judgments scored on a four-step scale (none, weak, moderate, strong). The matrix is intended to make the implicit attribution in any narrative Porter analysis visible and contestable rather than to claim quantitative precision. v2 of this build will ground each cell in either an explicit transmission mechanism or an empirical anchor (e.g., share of revenue at risk, observed historical comp). For now, treat the matrix as a structured prompt for stress-testing the per-force narratives against specific signal attributions.

Firm attribute matrix · 12 airlines × 8 attributes L2 canonical object

Each row is a major listed airline; each column is a firm attribute that determines exposure to one or more of the six active channels. Cell color = exposure intensity from green (insulated/positive) through gray (neutral) to red (severely exposed). All attributes coded with the convention that red represents current negative policy exposure — this matters for attributes like Pacific routing (currently negative due to Russia overflight, but structurally a strength in normal times) and SAF gap (where being a leader is green and being a laggard is red). Rows ordered by aggregate exposure least to most.

Exposure intensity: Insulated / positive Light positive Neutral Moderate exposure Significant exposure Severe exposure

Reading the matrix: the exposure pattern is unusually concentrated by firm-type rather than distributed across the row order. Domestic-only ULCCs and LCCs (top of table) are insulated from sanctions/kinetic/trade exposure but face elevated SAF gap and operational vulnerability. US legacies (DAL, AAL, UAL) cluster around medium-high exposure with the loyalty co-brand attribute being the framework's biggest hidden risk. European flag carriers (DLAKY, AFLYY, ICAGY) face the most severe multi-attribute exposure due to the combination of Asian routing penalty, EU regulatory load, and structural labor costs. The Boeing concentration column is the framework's biggest single attribute spread — from 0% (Airbus operators) to 100% (LUV, RYAAY) — and creates a binary risk that doesn't smoothly correlate with other exposures.

Methodology: attribute classifications drawn from 10-K segment disclosure, fleet manuals, IATA route filings, ASM data, and union contract status as of Q1 2026. Limits: percentages are point-in-time estimates and several attributes (especially Pacific routing burden, SAF gap) will move materially over 12–24 months as the underlying signals evolve. Loyalty co-brand revenue exposure is approximated from disclosed mileage program revenue and is necessarily imprecise because airlines disclose this differently.

Channel rollup · weighted exposure and tailwinds by channel bidirectional

Each cell aggregates the relevant signals' weighted scores into a single channel-level value. Negative exposure and positive tailwinds are reported separately rather than netted at the cell level — this preserves the analytical signal that a firm with high gross exposure offset by meaningful tailwinds is a different risk profile than a firm that is simply not in the line of fire. The summary table at the bottom collapses the two sides into a net score and ranks the universe.

Reading the rollup. The negative heatmap shows where each firm is hit; the positive heatmap shows where tailwinds offset that exposure. Most cells in the positive heatmap are empty — positive tailwinds in this sector are sparse and concentrated in two structural sources: Airbus fleet bias (which makes Boeing risk a relative tailwind) and slot-rich hub positions (which make slot tightening a competitive moat). The net summary table collapses both sides and produces the headline ranking that the synthesis section below interprets. Dispersion is 5.0× — UAL's net 85 versus JBLU's net 17 means the most exposed carrier in our coverage faces five times the policy headwinds of the least exposed. This is the framework's primary materiality measure for the sector.

Cross-signal interaction graph · how the fourteen signals compound at the P&L level

Aviation's cross-signal interactions are unusually clean because the same firm-attribute nodes (geography, fleet, labor, channel mix) take inputs from multiple signal categories. Read the graph as: signals on the left feed into intermediate firm-attribute nodes in the middle, which feed into the four P&L outcome nodes on the right. The dominant interaction pattern is geographic compounding — Russia overflight + Iran/Hormuz + EU regulatory load all converge on the routing-economics node for European Asian gateway carriers. The second pattern is the loyalty/regulatory compression on US legacies.

Key compounding pathways: (1) Geographic compounding — Russia overflight + Iran/Hormuz + ATC staffing all converge on routing economics, with the heaviest impact on European Asian-gateway carriers (DLAKY, AFLYY) where the routing penalty stacks with their existing structural cost disadvantage. (2) Boeing concentration — Section 232 + China retaliation + FAA enforcement intensity all flow through fleet composition into capacity and unit cost, hitting LUV/RYAAY/UAL most severely; the three signals are partially correlated because they all reflect Boeing-as-vulnerability. (3) Loyalty compression — CFPB/DOT loyalty inquiry feeds directly into the loyalty/non-flying margin node, which is concentrated in DAL, AAL, UAL; this is the framework's largest under-priced single risk because most peer analyses don't isolate the co-brand revenue contribution. (4) Cost stack accumulation for European carriers — SAF mandates + ETS phase-out + labor costs + Russia overflight all hit DLAKY/AFLYY simultaneously, which is why their channel rollup totals are the highest in the sector despite no single channel being individually catastrophic.

Industry structure & consolidation lever new L2 section meta-policy

Consolidation potential is a latent option that sits on every industry, and the FTC/DOJ posture toward M&A determines whether that option is exercisable. The reason this deserves a dedicated section rather than a single signal row is that the meaning of "compression case" depends entirely on whether the M&A door is open: a compression case in a permissive environment is potentially an acquisition target (the trade may be long-the-target rather than short-the-compression), while a compression case in a hostile environment is a pure long compression trade with no escape valve. Aviation is the canonical industry where this matters — the JetBlue/Spirit block (now historical) and the Alaska/Hawaiian approval-with-conditions established the current enforcement frontier, and any future US airline merger will be evaluated against that frontier. This section reads the current posture, assigns each firm a structural M&A role, and feeds into the synthesis layer below.

Current US enforcement posture

Restrictive · high bar

The DOJ Antitrust Division and DOT have maintained a hostile stance on horizontal airline consolidation since the JetBlue/Spirit block. The Alaska/Hawaiian approval signals that geographic complementarity remains acceptable but capacity overlap is not — any merger with meaningful trunk-route overlap should be considered effectively blocked under the current administration.

EU competition authority maintains a parallel hostile posture and has used remedies (slot divestitures, route concessions) to extract concessions from prior deals. The UK CMA has been the most consistently restrictive of the three major regulators. For practical purposes, all three Western jurisdictions are simultaneously closed to large-scale airline horizontal M&A.

Recent enforcement history

JetBlue/Spirit (blocked, 2024): trunk overlap on Northeast routes was the binding constraint. Alaska/Hawaiian (approved with conditions, 2024): geographic complementarity and small overlap allowed clearance. EU/Lufthansa-ITA (approved with concessions, 2024): slot divestitures at LIN and MUC required. JetBlue/American NEA (unwound, 2023): even joint venture coordination was found anticompetitive.

Coverage universe · structural M&A roles

Plausible acquirers

DAL UAL RYAAY ICAGY

Carriers with the balance sheet, market position, and management capacity to execute a meaningful acquisition if the M&A window opens. None can execute a large horizontal deal under current posture; their acquirer status is conditional on a posture shift or on geographically-complementary opportunities.

Plausible targets

JBLU ALK ALGT DLAKY AFLYY

Carriers whose strategic position, scale, or fragility makes them logical targets if a buyer existed. JBLU is the cleanest US case — the failed Spirit deal already established its strategic interest in scale. The European trio are structurally undervalued enough to be perpetual targets but EU/national protectionism creates a parallel barrier above and beyond competition law.

Excluded from M&A optionality

LUV AAL ACDVF

Carriers that are too large or too complex to be acquired in current market conditions, and lack the balance sheet to be a meaningful acquirer. LUV is too large for a domestic acquirer and faces a Boeing-concentration discount that hurts any potential bidder; AAL is too leveraged. ACDVF is structurally captive to Canadian regulation. These are pure standalone trades on policy and operations.

Feedback into the synthesis layer

The interaction with compression cases matters most. Of the three compression cases identified in the synthesis below (UAL, DLAKY, AFLYY), none has a viable M&A escape valve under current posture: UAL is too large to be acquired and too constrained to acquire; DLAKY and AFLYY face the EU competition authority plus national protectionism on top of the underlying multi-channel pressure. The compression case reading is therefore unalleviated by consolidation optionality — these are pure long compression trades. For relative winners, the inverse is true: JBLU and ALK appear as relative winners on policy exposure AND as plausible targets, which means a posture shift toward permissiveness would create a second positive catalyst on top of the existing thesis. ALGT is a target case but small enough that any deal would be idiosyncratic rather than structural. The signal to monitor is FTC/DOJ leadership posture — not specific deal announcements. A change in enforcement philosophy moves multiple firms simultaneously, while individual deal news moves one firm at a time. The signpost section below tracks this as a standalone watch item.

Synthesis · four firm clusters and what each one means bidirectional

Insulatednet 17–30 · lowest in universe

JBLU 17 ALGT 19 ALK 30

Domestic-only and quasi-domestic carriers that are simply not in the line of fire for most signals. Four of the six active channels (kinetic, sanctions, Pacific trade, fiscal SAF/ETS) penalize international and Pacific exposure that this group does not have. JBLU benefits additionally from Airbus fleet bias which converts Boeing delivery risk into a small tailwind.

What this means. The trade is not "buy these names" — the framework reads policy exposure, not absolute fundamentals. ALGT trades on balance-sheet concerns that are unrelated to policy; JBLU trades on the post-Spirit strategic question; ALK is digesting Hawaiian. The framework's reading is that policy headwinds are not the reason to be underweight any of these names, which inverts the consensus framing for 2026.

Resilient legaciesnet 48–54 · high gross, high offset

ICAGY 48 DAL 54

Carriers with significant gross negative exposure that is meaningfully offset by structural tailwinds. DAL has the highest gross exposure of any insulated-or-resilient firm (68) but also the highest tailwinds in the sector (14, from Airbus fleet bias, slot-rich JFK/LGA position, and SAF leadership). ICAGY combines transatlantic franchise strength with the LHR slot dominance that converts slot tightening into a competitive moat. This category only exists because of bidirectional scoring — under a single-score system both firms would be classified mid-pack with no signal that their net position is closer to insulated than to compression.

What this means. Both names are positioned to outperform their gross-exposure-only peers (AAL, the European trio) on a relative-value basis. The trade expression is long-DAL/short-AAL on a US legacy pair, and long-ICAGY/short-AFLYY on a European legacy pair, in both cases capturing the tailwind differential despite both names being on the same side of most signals individually.

Pressure casesnet 43–55 · concentration risk

RYAAY 43 LUV 47 ACDVF 55

Mid-tier net scores that disguise concentrated single-channel risk. LUV's 47 is dominated by Boeing dependency — weighted scores of 15 (Boeing delivery) plus 8 (FAA enforcement post-MAX) account for nearly half its total exposure on a single supplier relationship. RYAAY has the same Boeing concentration plus heavy EU regulatory cost stack (SAF + ETS at 16 combined). ACDVF carries Pacific routing exposure (12 from Russia overflight) without the offsetting hub strength that DAL/ICAGY enjoy.

What this means. These are firms where a single signal escalation can move them sharply into the compression category. LUV is the cleanest L3 candidate in the build because its risk is essentially binary on Boeing delivery reliability. RYAAY's risk is Boeing plus fuel (which makes it sensitive to both Iran/Hormuz escalation and Boeing China retaliation). The pressure cases are not currently compression cases but they have the thinnest margin for further deterioration.

Compression casesnet 59–85 · multi-channel pile-up

AFLYY 59 DLAKY 61 AAL 79 UAL 85

Multi-channel exposure across five or six channels with sparse offsetting tailwinds. UAL is the framework's most exposed carrier at net 85 — it carries weighted-15 scores on TWO 3× signals simultaneously (Russia overflight as the largest TPAC operator, US-China frequency caps as the largest US-China operator) plus weighted-15 on the CFPB loyalty inquiry as the legacy with the highest co-brand profitability dependency. AAL at net 79 is similar but with less Pacific concentration and worse balance sheet. The European pair (DLAKY, AFLYY) combines Asian gateway position with full EU regulatory cost stack and high labor costs.

What this means. Pure long-compression trades. None of the four has a viable M&A escape valve under current FTC/DOJ posture (per the industry structure section above), which means there is no embedded takeover put. The trade expressions are either directional shorts or relative-value pairs against the resilient legacies (DAL, ICAGY) that face similar gross exposure but have offsetting tailwinds. The European pair is particularly clean because the multi-channel pile-up is structural rather than cyclical.

Priced in vs. to be priced in · framework call on consensus positioning

Already in consensus (priced in)

Russia overflight ban as a permanent feature. Four years on, sell-side models treat the routing penalty as structural. Western Asian gateway carriers' cost disadvantage is in earnings estimates and in valuation multiples. The framework agrees this is appropriately reflected.
Iran war / Hormuz crude impact via fuel costs. Brent +71% YTD has been fully digested into Q1/Q2 estimate cuts. The fuel cost passthrough is transparent and modeled. Risk is symmetric — resolution of the conflict would unwind quickly.
EU ETS aviation extension cost. European carrier earnings models include the phase-out of free allowances and the resulting per-passenger cost. Lufthansa and AF-KLM have explicitly disclosed their ETS allowance positions.
Boeing production cap impact on delivery schedules. The constraint on fleet growth is reflected in capacity guidance for Boeing-heavy operators. Southwest's reduced 2026 growth is in consensus.
DOT consumer protection rules · refunds and family seating. Compliance costs are modest and have been disclosed; the implementation timeline is well-known. ULCC ancillary revenue erosion is in estimates.
FAA pilot age limit + 1500 hour rule status quo. Sell-side correctly assumes neither passes in the current Congress. The pilot supply constraint is in capacity models.
ATC delays as structural rather than transitory. Northeast hub disruption is now in operating cost assumptions for affected carriers.

Yet to be priced in (framework's edge)

The CFPB/DOT loyalty inquiry as an actionable enforcement risk. This is the framework's single largest priced/unpriced gap. The inquiry is treated by most sell-side as procedural and unlikely to result in material action. The framework's view: even modest enforcement on co-brand interchange or disclosure could compress US legacy profitability by 1–2 multiple turns. Delta and American are most exposed; the position size in consensus models does not reflect this.
The European compression case as a category trade. Sell-side analyzes Lufthansa, IAG, and Air France-KLM individually rather than as a category facing six-channel compounding. The framework's view: the structural disadvantage is category-wide and should be priced as such, not as idiosyncratic firm-level issues that consensus treats as company-specific.
SAF mandate cost pressure on non-EU operators with EU exposure. The cost-pass-through dynamics for non-EU carriers operating into EU airports under ReFuelEU are not well-modeled. UAL, DAL, AAL face partial exposure that is not in their cost guidance.
The ULCC/LCC relative-winner pattern on policy grounds. Consensus narratives still treat ULCCs as the most fragile sub-sector with the most exposure to bad outcomes. The framework reframes this: their fragility is real but it is not policy-driven, and the policy headwinds are concentrated on the international operators consensus considers the safer trade.
Boeing delivery risk as event-driven volatility. The China retaliation risk on Boeing deliveries is modeled as binary (it happens or it doesn't) when the realistic profile is recurring noise around the trade truce. LUV and AAL options markets do not price this volatility appropriately.
The interaction effect between Section 232 metals and MRO cost. Aircraft parts tariffs flowing through to maintenance costs is a slow burn that is not currently in unit cost guidance. The cumulative effect over 24 months is meaningful for older fleets.
Slot allocation tightening as a structural moat for legacies. The use-it-or-lose-it rule changes are not reflected in sell-side estimates as a competitive advantage for slot-rich carriers. DAL at JFK/LGA and ICAGY at LHR are the principal beneficiaries.

Signposts · what to watch over the next 6–12 months

Apr-May '26

CFPB/DOT loyalty inquiry status updates. Any procedural movement on airline credit card co-brand programs would re-rate US legacies sharply. Highest under-priced single signal in the sector.

Apr-Jun '26

Iran ceasefire durability and Hormuz status. Resolution unwinds the crude/jet fuel premium quickly; collapse re-anchors the cost stack at higher levels for the entire sector.

Q2 '26

Boeing delivery cadence Q2 reporting. Cumulative shortfall against revised guidance would compress LUV and RYAAY directly and benefit Airbus-heavier carriers (DAL, JBLU).

Q2-Q3 '26

US-China bilateral aviation talks status. Any movement on frequency caps would be a discrete event for UAL and AAL. Pre-positioning is difficult because timing is opaque; Treasury readouts are the early channel.

Summer '26

EU summer schedule adherence and ATC strike activity. European labor disruption is a recurring summer feature; severity is the swing factor for the European trio's Q3 results.

Q3 '26

FAA enforcement intensity update. LUV's institutional channel exposure depends heavily on whether FAA continues post-MAX heightened oversight or normalizes. Single-signal catalyst either way.

Q3-Q4 '26

SAF compliance reporting and EU ETS trajectory. European carriers report blend compliance and hedge positions; combined effect is the largest single cost driver for the European trio in 2026-27.

Ongoing

FTC/DOJ leadership posture on horizontal M&A. Not specific deal announcements but enforcement philosophy. A change moves multiple firms simultaneously by re-opening or further closing the consolidation lever for plausible targets (JBLU, ALK).

Methodology. The dashboard is built from publicly disclosed information as of April 8 2026. Firm attribute scores are derived from 10-K segment disclosures, IATA filings, fleet databases, and route planning data. Bidirectional signal scores (negative exposure 0–5 and positive tailwind 0–5) are analyst judgments calibrated against transmission mechanisms specific to each signal; weights (1×/2×/3×) reflect the peak impact of each signal on sector EBIT. Channel rollups are linear sums of weighted signal scores. The signal-to-force matrix in the Porter section uses a four-step intensity scale (none, weak, moderate, strong). Probability weights for individual signal scenarios are not provided at L2 — they belong to L3 deep-dives.

Coverage. Twelve listed passenger airlines representing the largest carriers in the US, Europe, and Canada. The framework excludes cargo airlines, lessors, MRO, and aircraft manufacturers; signals affecting these segments are treated as exogenous inputs to the passenger airline analysis. Regional and smaller carriers are excluded from the coverage universe but their dynamics are captured in the relevant signals where they affect the covered firms.

Limits. Scores reflect analyst judgment rather than quantitative model output. The bidirectional scoring distinguishes negative exposure from positive tailwind but does not attempt to quantify dollar P&L impact — for that, the relevant L3 deep-dive on a specific signal is required. The most directly stress-testable element is the per-firm net ranking, which can be compared against realized relative performance over the next 6–12 months.

Updating. The dashboard is re-versioned when material new signals enter the inventory, when existing signals change maturity status, or when scoring revisions are warranted by observed implementation details. The signposts section above identifies the specific events that would trigger a re-version.

All six policy channels active simultaneously. Sector environment is overwhelmingly negative, with positive tailwinds clustered in fleet bias and slot positions rather than distributed across the universe.
