Methodology

Source

AirBQ Cohort A uses official BTS Airport Snapshot pages. Each HTML response is stored as an immutable snapshot, hashed, parsed by explicit labels and table headings, and validated before export.

Semantics

Average delay values refer to delayed flights only. The rolling period is 2025-07 – 2026-06.

Scope

These are reference statistics, not real-time flight information or recommendations.
