Airline fares is attached to Domestic airlines as a broad BLS consumer-price context series. Consumer airline fares are broad transportation-price context for the airline dossier; they do not identify route markets, airline margins, capacity effects, or competitive causation.

Graph contract
Relationship families stay separate
The atlas joins routes through encoded custody and context, never through name resemblance or an inferred corporate, legal, or causal relationship.
The atlas exposes only relationships declared in the current public data. A link or issue grouping does not make unlike measures comparable, establish ownership or control, define an antitrust market, assign liability, or show that a policy event caused an economic outcome.
Reusable graph packet
Carry node and edge custody into analysis
The packet preserves node type, canonical route, relationship family, source link, evidence label, confidence, and edge-specific guardrail.
