Departure window
The best time of day to leave DAL in July
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 46 points, against half a point between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am927 flights93.2%
- 8am–11am1,168 flights85.0%
- 11am–2pm1,143 flights74.3%
- 2pm–5pm1,070 flights60.5%
- 5pm–8pm1,069 flights47.1%
- 8pm–5am972 flights49.1%
Scale runs 40% to 100%. Rows with fewer than 30 flights show a dash.
The 5pm–8pm window is where this operation falls apart: 47.1% on time, against 93.2% for the 5am–8am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 8am–11am window is the busiest, with 1,168 flights scheduled in it.
Across the week, Friday is the strongest day at 79.3% on time and Sunday the weakest at 62.9%. 16 points is a smaller lever than departure hour, but it is free.

Delay causes
What held DAL up in July
One category carries most of the weight here. Late-arriving aircraft accounts for 48% of the 121,000 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.
- 48%Late-arriving aircraft
- 29%Carrier
- 17%National Airspace System
- 5%Extreme weather
- 0%Security
48% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 121,000 reported delay minutes here, that single category outweighs weather by 9 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 121,168 reported delay minutes.
Cancellations sit at 1.32% against a national 2.45%, which is ordinary. Diversions add another 0.38%.
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 10.9% of arrivals land a full hour or more behind schedule, against 12.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.
What to do with this
Flying from DAL in July
For a July trip through DAL: plan on this being one of the airport's harder months. The 5am–8am departures held up best at 93.2% on time, and with 10.9% of arrivals an hour or more late, a connection here deserves more slack than the same trip in January would.
