Across the year
DL 763 quarter by quarter
DL 763 did not run the same all year. Its best quarter was Oct–Dec 2025 at 79.5% on time and its weakest Jul–Sep 2026 at 40.3%, a swing of 39 points on roughly 72 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

By weekday, DL 763 did best on Wednesday at 70.7% on time and worst on Sunday at 58.5%. Each day rests on about 41 flights, so a gap of 12 points is worth noticing but could still narrow in another year.

Share of 284 completed flights by arrival against schedule.
21 of 103 late departures made up the time and arrived on time, 20% of them. In the other direction, 21 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 LAX.
The worst days
Worst days for DL 763
The latest arrival of the period was on 27 August 2026, 14 hours 47 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 27 August 2026 | 14 hours 47 minutes | Carrier |
| 18 June 2026 | 3 hours 13 minutes | Extreme weather |
| 7 May 2026 | 3 hours 1 minute | Late-arriving aircraft |

Delay causes
Why DL 763 runs late
Carrier accounts for 58% of the 5,825 delay minutes carriers reported here, and the remaining four split what is left.

- 2%Security
The largest share of delay minutes, 58%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 3,386 of the 5,825 delay minutes reported here. The split is drawn from 5,825 delay minutes reported on DL 763.
Cancellations are rare at 0.70%, below the national 1.89% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.
Connections and routes
What a delay on this flight costs
9.2% 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.
At 1,947 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 four other city pairs in the data, including DTW to ORF (49), ORF to DTW (49) and ATL to TRI (1), but none flew often enough under DL 763 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ATL to LAX only.
One caution: this is a thin sample. 286 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.
