PlainFlights Reliability Score
Transparent derived index from BTS On-Time Performance data — not an official DOT/FAA rating.
- On-Time Rate F
73.7%
Share of flights arriving within the BTS 15-minute on-time threshold
- Delay Severity F
80 min
Total arrival-delay minutes (all flights, including delays under 15 min) divided by the flights that arrived 15+ min late
- Cancellation Rate D
2.40%
Share of scheduled flights cancelled
Weighted from on-time rate, delay minutes per late flight, and cancellation rate, each scored against the 18 currently tracked U.S. carriers with meaningful flight volume (percentile method). A dimension without a reported value drops out and its weight redistributes to the rest — missing data never deflates the score. See the full formula, weights, and live benchmark table.
