What each reason means

Reason codes are the operating airline’s own filing with US DOT, not an independent finding of fault. Ordinary bad weather is filed under air traffic, so weather’s full share is larger than its bar.

460 coded cancellations were recorded on ORD → DCA; the section appears from 50.

ORD → DCA has an average that understates its risk: a typical arrival is 3 min early, but the worst tenth are 66 minutes worse than that. If the trip has something unmissable at the end of it, the median is the wrong number to plan against.

Percentiles over 20,159 operations; cancelled and diverted flights are counted separately.

This is one leg of a connection. Gate changes and the next flight's own schedule matter too. And a connection can fail before delay is even the question — this route cancels 2.28% of the time and diverts 0.55% of the time, which a late arrival never shows up in.

Chance of missing is the share of 19,588 arrivals on this route that landed later than the connection time less 30 minutes to reach the next gate.

The worst tenth of arrivals on this route land at least 63 minutes late (90th-percentile gate arrival delay), over 20,159 operations.
