Departure window

The best time of day to leave DAL in August

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 30 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–8am700 flights93.2%
  • 8am–11am1,130 flights84.3%
  • 11am–2pm1,178 flights76.7%
  • 2pm–5pm1,123 flights71.0%
  • 5pm–8pm984 flights63.5%
  • 8pm–5am615 flights64.4%

Scale runs 55% to 100%. Rows with fewer than 30 flights show a dash.

The 5pm–8pm window is where this operation falls apart: 63.5% 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 11am–2pm window is the busiest, with 1,178 flights scheduled in it.

Across the week, Tuesday is the strongest day at 88.5% on time and Sunday the weakest at 70.3%. 18 points is a smaller lever than departure hour, but it is free.

Delay causes

What held DAL up in August

One category carries most of the weight here. Late-arriving aircraft accounts for 51% of the 85,000 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.

  • Late-arriving aircraft
    51%
  • Carrier
    25%
  • National Airspace System
    19%
  • Extreme weather
    5%
  • Security
    0%

51% 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 85,000 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 85,042 reported delay minutes.

Cancellations are rare at 0.54%, below the national 1.08% 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.

8.0% of arrivals land an hour or more late, close to the national 8.2%. That is the figure that decides a connection, and it says 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.

What to do with this
