BTS operating-flight/T-100 records · FAA boardings · retrieved 2026-10-03
Reliability uses BTS domestic Reporting Carrier On-Time Performance, 2019–2025. Each operating flight is counted once. Arrival on time means an observed arrival delay below 15 minutes, excluding canceled, diverted and missing outcomes. Departure on time uses observed departures, excluding canceled and missing outcomes. Cancellations and diversions use all scheduled records. Delay averages use nonnegative lateness minutes, including zero for early arrivals/departures.
Comparisons apply identical dates, month, carrier, destination, weekday and origin-local scheduled departure hours. A rate needs 100 eligible records to rank; smaller samples are displayed and labeled. Cause minutes describe eligible late-arriving flights with reported causes; they are not proportions of all passengers or all flights. Cancellation causes are carrier, weather, national air system, security and unknown.
T-100 domestic/international all-carrier segments represent recorded scheduled (F) or nonscheduled (L) passenger service. Departures and passenger movements are directional; seats and passengers are not unique travelers. Historical routes do not promise future service. FAA enplanements are passenger boardings, not arrivals plus departures. Airport/carrier stable BTS IDs retain observed code histories; unmatched or ambiguous locations remain unlocated. Current coordinates use FAA NASR 2026-10-01 and unique OurAirports IATA matches.
