Historical statistics for June 2026, not live status or a forecast for this year’s June. For today’s conditions at DFW, see live FAA status.

DFW in June carries a cancellation problem, not just a delay problem: 4.5% of scheduled flights never operate, against 1.6% nationally. Of the ones that do fly, about two flights in three arrive on time, worth a D− overall. The punctuality figure counts only flights that actually departed, so it flatters an operation that cancels this often. That rests on 27,815 flights, of which Delta Air Lines flew 946 at 76.4% on time.

Delta Air Lines is the most reliable of the seven carriers covered here at 76.4% on time across 946 flights.

These figures cover 27,815 departures from Dallas/Fort Worth International in June 2026. 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

June next to DFW's other months

Against DFW's own year, June ran 8 points worse than the twelve-month rate of 72.0%, which makes it the worst of the twelve months in the data. Cancellations are where June stands out: 4.55% of scheduled departures were called off, 1.5 times the airport's rate across the year.

Departure window

The best time of day to leave DFW in June

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 26 points, against 21 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

  • 5am–8am2,742 flights79.8%
  • 8am–11am5,552 flights76.0%
  • 11am–2pm4,561 flights64.8%
  • 2pm–5pm4,615 flights57.2%
  • 5pm–8pm4,669 flights55.8%
  • 8pm–5am5,676 flights53.8%

Scale runs 45% to 85%. Rows with fewer than 30 flights show a dash.

The 8pm–5am window is where this operation falls apart: 53.8% on time, against 79.8% 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 8pm–5am window is the busiest, with 5,676 flights scheduled in it.

Across the week, Wednesday is the strongest day at 77.0% on time and Sunday the weakest at 51.7%. 25 points is a smaller lever than departure hour, but it is free.

Carrier by carrier

Which airlines ran best at DFW in June

The choice of carrier is not cosmetic here. Delta Air Lines arrives on time 76.4% of the time; American Airlines manages 55.0%. Sample sizes sit next to every figure, because a two-point gap across 14,398 flights means less than a ten-point one.

Delay causes

What held DFW up in June

One category carries most of the weight here. Late-arriving aircraft accounts for 50% of the 790,000 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
    50%
  • Carrier
    26%
  • National Airspace System
    13%
  • Extreme weather
    11%
  • Security
    0%

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 1.7 times the usual weather exposure. The split is drawn from 790,231 reported delay minutes.

Cancellations run at 4.55%, against 1.65% nationally. That is roughly one flight in twenty 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. 16.4% of arrivals land a full hour or more behind schedule, against 9.7% 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 June

For a June trip through DFW: plan on this being one of the airport's harder months. The 5am–8am departures held up best at 79.8% on time, and with 16.4% of arrivals an hour or more late, a connection here deserves more slack than the same trip in February would.
