Other routes DL796 has flown
A flight number is a slot in a schedule, and carriers reassign it. These are the other city pairs this number served in the analysis period.
| Route | Operated | Flights | On time |
|---|---|---|---|
| PHX→ATL Phoenix to Atlanta | 2023-07-01 – 2026-06-30 | 982 | 81.8% |
Because the same number has served different journeys, the statistics above describe only the route DL796 currently operates. Blending them would produce an average of two different flights.
Why DL796 runs late
Where US DOT attributed the delay minutes on this flight.
crew, maintenance, boarding, fuelling — within the carrier’s control
the inbound aircraft was late, so this flight started late
airspace and airport capacity, including weather-driven flow control
weather severe enough to stop this flight specifically
Share of the delay minutes US DOT attributed to each cause for DL796 on ATL → PHX. A single late flight can carry more than one cause, and only delays of fifteen minutes or more are attributed at all.
Other departures on ATL → PHX
Same airports, same journey — and not the same odds of arriving on time.
| Flight | Airline | On time | Median arrival | Operations |
|---|---|---|---|---|
| DL348 | Delta Air Lines | 77.4% | 2 min late | 816 |
| DL339 | Delta Air Lines | 75.3% | 1 min early | 667 |

| DL757 | Delta Air Lines | 71.3% | 0 min early | 830 |
Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. Schedules change; confirm the departure still operates before booking around this.
Data and methodology
Calculated by FlyerIntel from 1,070 records of DL796 operating ATL → PHX, published by the US DOT Bureau of Transportation Statistics. A flight counts as delayed when it arrives 15 or more minutes after schedule. Cancelled and diverted flights are excluded from the on-time rate and reported separately. Flight numbers are resolved as carrier plus number plus route, because the same number serves different routes over time.
