These figures cover 340 flights between September 2025 and August 2026. The median arrival is 9 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Delay causes
Why YX 5692 runs late
National Airspace System accounts for 62% of the 1,640 delay minutes carriers reported here, and the remaining four split what is left.
- 62%National Airspace System
- 26%Carrier
- 8%Extreme weather
- 5%Late-arriving aircraft
62% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 1,015 minutes out of 1,640, against a national NAS share of 21%. The split is drawn from 1,640 delay minutes reported on YX 5692.
Cancellations sit at 2.06% against a national 1.89%, which is ordinary. Diversions add another 0.29%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 3.0% land an hour or more behind schedule, against 8.3% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
The same number turns up on one other city pair in the data, including DCA to BOS (60), but none flew often enough under YX 5692 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to BOS to DCA only.
One caution: this is a thin sample. 340 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.
What to do with this
Booking YX 5692
