Delay causes
Why UA 2398 runs late
Late-arriving aircraft accounts for 53% of the 8,854 delay minutes carriers reported here, and the remaining four split what is left.
- 53%Late-arriving aircraft
- 28%Carrier
- 19%National Airspace System
53% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 8,854 reported delay minutes here, that single category outweighs weather by 53 to one. The split is drawn from 8,854 delay minutes reported on UA 2398.
Cancellations run at 2.50%, against 1.89% nationally. That is about one flight in 40 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
14.2% 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 three other city pairs in the data, including FLL to EWR (32), MIA to EWR (21) and TPA to EWR (21), but none flew often enough under UA 2398 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to EWR to CLE only.
One caution: this is a thin sample. 360 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 UA 2398
For a booking, the cancellation rate is the figure to plan around on UA 2398: 2.50% of its 360 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.
