Historical statistics for August 2025, not live status or a forecast for this year’s August. For today’s conditions at DFW, see live FAA status.
DFW in August draws a C. About one flight in three arrives at least 15 minutes late, and the typical late arrival is a little over an hour behind schedule. Build slack into anything you connect to. That rests on 27,091 flights, of which Delta Air Lines flew 1,050 at 81.1% on time.
Delta Air Lines is the most reliable of the eight carriers covered here at 81.1% on time across 1,050 flights.

These figures cover 27,091 departures from Dallas/Fort Worth International in August 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
August next to DFW's other months
Against DFW's own year, August ran 6 points worse than the twelve-month rate of 72.0%, which makes it number ten of twelve months, best first. Either side of it, July ran 64.3% on time and September 77.4%, 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 August
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 27 points, against 25 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am2,623 flights81.2%
- 8am–11am5,638 flights76.7%
- 11am–2pm4,584 flights68.2%
- 2pm–5pm5,032 flights60.5%
- 5pm–8pm5,118 flights54.1%
- 8pm–5am4,096 flights58.6%
Scale runs 45% to 85%. Rows with fewer than 30 flights show a dash.
The 5pm–8pm window is where this operation falls apart: 54.1% on time, against 81.2% 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 5,638 flights scheduled in it.
Across the week, Tuesday is the strongest day at 71.3% on time and Sunday the weakest at 59.6%. 12 points is a smaller lever than departure hour, but it is free.
Carrier by carrier
Which airlines ran best at DFW in August
The choice of carrier is not cosmetic here. Delta Air Lines arrives on time 81.1% of the time; American Airlines manages 56.4%. Sample sizes sit next to every figure, because a two-point gap across 13,659 flights means less than a ten-point one.

American Airlines cancels 3.6% of what it schedules here, the highest in the table. A cancelled flight never appears in an on-time rate, so read that column alongside the punctuality one rather than after it.

Delay causes
What held DFW up in August
One category carries most of the weight here. Late-arriving aircraft accounts for 49% of the 718,000 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.
- 49%Late-arriving aircraft
- 26%Carrier
- 13%National Airspace System
- 11%Extreme weather
- 0%Security
Extreme weather accounts for 11% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the comparison with the other months below is the more useful view of the risk. The national share is 7%, so this operation carries roughly 1.6 times the usual weather exposure. The split is drawn from 717,839 reported delay minutes.
Cancellations run at 2.66%, against 1.08% nationally. That is about one flight in 40 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 14.2% of arrivals land a full hour or more behind schedule, against 8.2% 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 August
For a August trip through DFW: plan on this being one of the airport's harder months. The 5am–8am departures held up best at 81.2% on time, and with 14.2% of arrivals an hour or more late, a connection here deserves more slack than the same trip in February would.
