These figures cover 264 flights between September 2025 and August 2026. The median arrival is 12 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 5710 runs late

- 74%Carrier
- 26%National Airspace System
The largest share of delay minutes, 74%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 663 of the 896 delay minutes reported here. The split is drawn from 896 delay minutes reported on YX 5710.
Cancellations run at 3.03%, against 1.89% nationally. That is roughly one flight in 30 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 2.7% 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 three other city pairs in the data, including SAV to BOS (2), DTW to GRR (2) and BOS to SAV (2), but none flew often enough under YX 5710 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DCA to BOS only.
One caution: this is a thin sample. 264 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 5710
For a booking, the cancellation rate is the figure to plan around on YX 5710: 3.03% of its 264 scheduled flights did not operate. A late arrival costs about 50 minutes, but a cancellation costs the day, so leave a later option open.
