Historical statistics for July 2025 to June 2026, not live status. For today’s YX 5699, check with Republic Airways. Republic Airways flies under contract for larger airlines, so a ticket for this flight may show a different airline code and number.

YX 5699 draws a D−. Roughly one flight in two arrives at least 15 minutes late, and the typical late arrival is a little over an hour behind schedule. Build slack into anything you connect to. That rests on 349 flights, with a median arrival 7 minutes late.

These figures cover 349 flights between July 2025 and June 2026. Beyond the headline rate, 16.5% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Schedule

When YX 5699 flies

YX 5699 flies JFK to DCA without a single fixed slot. Its most common scheduled departure was 14:59, used on 62 of 349 flights, with 16:20 (41 flights) and 15:30 (36 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 14:59 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and YX 5699 runs 13 points worse at 59.8%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

YX 5699 quarter by quarter

YX 5699 did not run the same all year. Its best quarter was Oct–Dec 2025 at 75.3% on time and its weakest Jan–Mar 2026 at 38.8%, a swing of 37 points on roughly 87 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.

By weekday, YX 5699 did best on Saturday at 72.3% on time and worst on Sunday at 47.7%. Each day rests on about 50 flights, so a gap of 25 points is worth noticing but could still narrow in another year.

Delay causes

Why YX 5699 runs late

One category carries most of the weight here. National Airspace System accounts for 55% of the 9,848 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

55% 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 5,444 minutes out of 9,848, against a national NAS share of 21%. The split is drawn from 9,848 delay minutes reported on YX 5699.

Cancellations run at 5.73%, against 1.81% nationally. That is roughly one flight in fifteen 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

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 16.5% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.

The same number turns up on one other city pair in the data, including DCA to JFK (16), but none flew often enough under YX 5699 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to JFK to DCA only.

One caution: this is a thin sample. 349 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 5699

For a booking, the cancellation rate is the figure to plan around on YX 5699: 5.73% of its 349 scheduled flights did not operate. A late arrival costs a little over an hour, but a cancellation costs the day, so leave a later option open.
