What are the odds your flight is late?
Compare on-time arrivals, long delays and cancellations for U.S. airport pairs—with the airline, departure time, weekday and monthly evidence behind every number.
Enter three-letter U.S. airport codes. Historical results for July 2025–June 2026.
Direction, time and airline all change the odds.
A national average cannot tell you whether the 6 a.m. flight from Boston to Chicago is a safer bet than the evening departure. DelayOdds keeps the comparison at route level, then shows the slices that can actually inform a booking decision.
Every percentage links back to its sample and time window. No hidden “AI score,” no live-status theatre.
Routes that kept the schedule
Three numbers. One honest sample.
On-time odds
The share of every scheduled reportable flight that completed and arrived less than 15 minutes after schedule.
Disruption odds
See 30-, 60- and 120-minute delay rates alongside cancellations and diversions. They are not blended away.
Useful comparisons
Check airline, time-of-day, weekday and month tables. Thin samples are withheld instead of dressed up as certainty.
