These figures cover 252 flights between September 2025 and August 2026. The median arrival is 8 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.

A 08:50 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 83.9%, and YX 5742 runs level with that at 82.8%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year

YX 5742 quarter by quarter

YX 5742 did not run the same all year. Its best quarter was Jan–Mar 2026 at 85.7% on time and its weakest Jul–Sep 2026 at 75.4%, a swing of 10 points on roughly 84 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

Scale runs 65% to 90%. Rows with fewer than 30 flights show a dash.

By weekday, YX 5742 did best on Wednesday at 91.7% on time and worst on Monday at 78.8%. Each day rests on about 36 flights, so a gap of 13 points is worth noticing but could still narrow in another year.

Arrival by arrival

How late YX 5742 runs when it is late

YX 5742 often beats the schedule: 80 of 244 completed flights, 33%, arrived 15 minutes or more early. The 42 late arrivals split 15 under half an hour, 19 between 30 and 60 minutes, and 8 an hour or more.

Share of 244 completed flights by arrival against schedule.

Time lost at the gate mostly stays lost. Of 22 departures that left 15 minutes late or more, only 2 made it up before arrival. In the other direction, 22 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at DCA.

Delay causes

Why YX 5742 runs late

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 2,440 reported delay minutes.

Carrier
40%
National Airspace System

Security

The largest share of delay minutes, 40%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 979 of the 2,440 delay minutes reported here. The split is drawn from 2,440 delay minutes reported on YX 5742.

Cancellations run at 3.17%, against 1.89% nationally. That is about 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 3.3% 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 four other city pairs in the data, including DCA to LGA (203), LGA to BOS (84) and LGA to CLT (5), but none flew often enough under YX 5742 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to LGA to DCA only.

One caution: this is a thin sample. 252 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 5742

For a booking, the cancellation rate is the figure to plan around on YX 5742: 3.17% of its 252 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
