These figures cover 25,770 departures from Dallas/Fort Worth International in December 2025. On time means an arrival less than 15 minutes after the scheduled gate time, the DOT's threshold, and the national comparison uses every US departure in the same month rather than the whole year.

Against the year

December next to DFW's other months

Against DFW's own year, December ran level with the twelve-month rate of 72.0%, which makes it number nine of twelve months, best first. Cancellations were unusually low for DFW in December, at 0.62% against 2.97% across the year. Either side of it, November ran 74.3% on time and January 75.4%, so a trip moved by a few weeks would have landed in a better stretch.

Departure window

The best time of day to leave DFW in December

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 18 points, against 19 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

  • 5am–8am2,457 flights81.7%
  • 8am–11am5,594 flights78.8%
  • 11am–2pm4,378 flights73.8%
  • 2pm–5pm4,622 flights68.9%
  • 5pm–8pm5,008 flights63.4%
  • 8pm–5am3,711 flights66.9%

Scale runs 55% to 85%. Rows with fewer than 30 flights show a dash.

The 5pm–8pm window is where this operation falls apart: 63.4% on time, against 81.7% 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 5,594 flights scheduled in it.

Across the week, Wednesday is the strongest day at 77.0% on time and Sunday the weakest at 63.2%. 14 points is a smaller lever than departure hour, but it is free.

Carrier by carrier

Which airlines ran best at DFW in December

The choice of carrier is not cosmetic here. Envoy Air arrives on time 84.4% of the time; American Airlines manages 65.7%. Sample sizes sit next to every figure, because a two-point gap across 13,864 flights means less than a ten-point one.

Delay causes

What held DFW up in December

One category carries most of the weight here. Late-arriving aircraft accounts for 49% of the 485,000 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
    49%
  • Carrier
    38%
  • National Airspace System
    11%
  • Extreme weather
    3%
  • Security
    0%

49% 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 485,000 reported delay minutes here, that single category outweighs weather by 18 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 484,996 reported delay minutes.

Cancellations are rare at 0.62%, below the national 1.55% 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.

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 9.7% of arrivals land a full hour or more behind schedule, against 10.0% 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 DFW in December

For a December trip through DFW: expect 71.7% on time and 0.62% cancelled, going by December 2025. The 5am–8am window was the strongest part of the day.
