These figures cover 364 flights between September 2025 and August 2026. The median arrival is 8 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.

The largest share of delay minutes, 84%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 3,541 of the 4,231 delay minutes reported here. The split is drawn from 4,231 delay minutes reported on DL 761.
Cancellations sit at 1.92% against a national 1.89%, which is ordinary. Diversions add another 1.10%.
Connections and routes
What a delay on this flight costs
5.4% 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 close to two hours, which a normal layover absorbs.
At 1,900 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.
The same number turns up on one other city pair in the data, including ATL to ONT (60), but none flew often enough under DL 761 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ONT to ATL only.
One caution: this is a thin sample. 364 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 DL 761
