Having 1 carrier on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 9,345 total flights analyzed, the 87.7% on-time figure is statistically meaningful rather than a small-sample fluke. The 61.8-minute average delay applies only to flights that actually ran late, so it is not the average wait across all departures — the majority of flights on this route depart on time under the BTS definition of a delay (15+ minutes past schedule).

Looking at recent months, Oct 2024 posted the best performance on this corridor at 97% on-time, while Jul 2024 came in at 76% on-time — a 21-point gap between best and worst recent month. For travelers evaluating the BUF to BWI route, the combination of a 87.7% on-time rate, 61.8-minute average delay, 1.3% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
