Share of 254 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 56 departures that left 15 minutes late or more, only 4 made it up before arrival. In the other direction, 28 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 4621 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 6,709 reported delay minutes.
- 40%National Airspace System
- 29%Late-arriving aircraft
- 26%Extreme weather
- 5%Carrier
Extreme weather accounts for 26% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 4.3 times the usual weather exposure. The split is drawn from 6,709 delay minutes reported on YX 4621.
Cancellations run at 3.77%, against 1.89% nationally. That is about one flight in 25 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
15.0% 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.
The same number turns up on one other city pair in the data, including JAN to DCA (11), but none flew often enough under YX 4621 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ORF to LGA only.
One caution: this is a thin sample. 265 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 4621
For a booking, the cancellation rate is the figure to plan around on YX 4621: 3.77% of its 265 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.
