Time lost at the gate mostly stays lost. Of 136 departures that left 15 minutes late or more, only 15 made it up before arrival. In the other direction, 43 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 LGA.

Delay causes
Why YX 5763 runs late
National Airspace System accounts for 46% of the 14,000 delay minutes carriers reported here, and the remaining four split what is left.
- 46%National Airspace System
- 34%Late-arriving aircraft
- 19%Carrier
- 1%Extreme weather
46% 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 6,254 minutes out of 14,000, against a national NAS share of 21%. The split is drawn from 13,739 delay minutes reported on YX 5763.
Cancellations run at 9.51%, against 1.89% nationally. That is about 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
25.8% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
Every one of the 347 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. 347 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: 9.51% of its 347 scheduled flights did not operate. A late arrival costs an hour and a half, but a cancellation costs the day, so leave a later option open.
