Across the year

Share of 250 completed flights by arrival against schedule.
13 of 87 late departures made up the time and arrived on time, 15% of them. In the other direction, 18 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 XNA.

Worst days for YX 4554
The latest arrival of the period was on 3 December 2025, 5 hours 15 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on three of the five worst days.

Delay causes
Why YX 4554 runs late
Late-arriving aircraft accounts for 55% of the 7,105 delay minutes carriers reported here, and the remaining four split what is left.
- 55%Late-arriving aircraft
- 21%National Airspace System
- 19%Carrier
- 5%Extreme weather
55% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 7,105 reported delay minutes here, that single category outweighs weather by 11 to one. The split is drawn from 7,105 delay minutes reported on YX 4554.
Cancellations run at 8.60%, against 1.89% nationally. That is about one flight in twelve 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
18.0% 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 1,147 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
The same number turns up on two other city pairs in the data, including LGA to AVL (12) and LGA to BOS (4), but none flew often enough under YX 4554 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to LGA to XNA only.
One caution: this is a thin sample. 279 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 4554
For a booking, the cancellation rate is the figure to plan around on YX 4554: 8.60% of its 279 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.
