These figures cover 300 flights between September 2025 and August 2026. The median arrival is 13 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Delay causes
Why UA 1445 runs late
Late-arriving aircraft accounts for 60% of the 2,941 delay minutes carriers reported here, and the remaining four split what is left.
- 60%Late-arriving aircraft
- 22%National Airspace System
- 17%Carrier
- 1%Extreme weather
60% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 2,941 reported delay minutes here, that single category outweighs weather by 60 to one. The split is drawn from 2,941 delay minutes reported on UA 1445.
Cancellations sit at 1.00% against a national 1.89%, which is ordinary. Diversions add another 1.00%.
Connections and routes
What a delay on this flight costs
6.1% 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 an hour, which a normal layover absorbs.
At 1,606 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 300 flights under UA 1445 in the data flew STT to IAD. 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. 300 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.
