Delay causes
Why UA 2219 runs late
Late-arriving aircraft accounts for 61% of the 8,595 delay minutes carriers reported here, and the remaining four split what is left.
- 61%Late-arriving aircraft
- 26%Carrier
- 11%Extreme weather
- 2%National Airspace System
61% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 8,595 reported delay minutes here, that single category outweighs weather by 6 to one. The split is drawn from 8,595 delay minutes reported on UA 2219.
Cancellations sit at 1.37% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
8.6% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about 2.4 hours, which a normal layover absorbs.
At 1,608 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.
Every one of the 365 flights under UA 2219 in the data flew SJU to EWR. 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. 365 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.
