Historical statistics for July 2025 to June 2026, not live status. For today’s YX 5763, 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 5763 earns an F−, which is as low as this site's scale goes for a reason. Only 51.9% of flights arrive inside the 15-minute window, 26 points worse than the national rate of 77.6%. Late arrivals average a little over an hour. Treat any tight connection here as a coin flip. That rests on 348 flights, with a median arrival 12 minutes late.

The national on-time rate over the same period is 77.6%, so YX 5763 runs 26 points behind the country as a whole. Across a thousand flights that is about 257 extra late arrivals.

These figures cover 348 flights between July 2025 and June 2026. Beyond the headline rate, 22.5% 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 5763 flies

YX 5763 flies DCA to LGA without a single fixed slot. Its most common scheduled departure was 17:50, used on 117 of 348 flights, with 17:40 (77 flights) and 17:10 (62 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 17:50 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and YX 5763 runs 16 points worse at 51.9%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year

YX 5763 quarter by quarter

YX 5763 did not run the same all year. Its best quarter was Jul–Sep 2025 at 63.0% on time and its weakest Jan–Mar 2026 at 42.1%, a swing of 21 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.

Jan–Mar 202687 flights42.1%

Scale runs 35% to 70%. Rows with fewer than 30 flights show a dash.

By weekday, YX 5763 did best on Saturday at 87.5% on time and worst on Thursday at 34.9%. Each day rests on about 50 flights, so a gap of 53 points is worth noticing but could still narrow in another year.

Delay causes

Why YX 5763 runs late

One category carries most of the weight here. National Airspace System accounts for 52% of the 12,000 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.

52% 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 6,179 minutes out of 12,000, against a national NAS share of 21%. The split is drawn from 11,863 delay minutes reported on YX 5763.

Cancellations run at 9.20%, against 1.81% nationally. That is roughly one flight in ten 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. 22.5% 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.

Every one of the 348 flights under YX 5763 in the data flew DCA to LGA. The number was not reused on any other city pair, which makes this a clean record of one route.

One caution: this is a thin sample. 348 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 5763

For a booking, the cancellation rate is the figure to plan around on YX 5763: 9.20% of its 348 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.
