These figures cover 332 flights between September 2025 and August 2026. The median arrival is 11 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.

- 77%Carrier
- 20%National Airspace System

- 0%Extreme weather
The largest share of delay minutes, 77%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,480 of the 1,924 delay minutes reported here. The split is drawn from 1,924 delay minutes reported on YX 5698.
Cancellations run at 2.71%, against 1.89% nationally. That is about one flight in 40 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 4.3% 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 CLE to LGA (12), but none flew often enough under YX 5698 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. 332 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 5698
For a booking, the cancellation rate is the figure to plan around on YX 5698: 2.71% of its 332 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
