These figures cover 313,000 flights between July 2025 and June 2026. Beyond the headline rate, 10.8% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.
Carrier by carrier
Which airlines run best out of DFW
The choice of carrier is not cosmetic here. Envoy Air arrives on time 82.1% of the time; American Airlines manages 65.9%. Sample sizes sit next to every figure, because a two-point gap across 164,581 flights means less than a ten-point one.

PSA Airlines cancels 4.4% 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.

Departure window
The best time of day to leave DFW
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 21 points, against 16 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am29,531 flights84.5%
- 8am–11am64,330 flights81.2%
- 11am–2pm54,446 flights73.9%
- 2pm–5pm54,261 flights67.9%
- 5pm–8pm59,013 flights63.8%
- 8pm–5am51,270 flights64.5%
Scale runs 55% to 90%. Rows with fewer than 30 flights show a dash.
The 5pm–8pm window is where this operation falls apart: 63.8% on time, against 84.5% 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 64,330 flights scheduled in it.
Across the year
When DFW runs late
DFW's year swings by 15 points from best month to worst, which is wide. An annual average tells you very little about the week you are actually flying, so read the strip rather than the headline if your dates are fixed.
June is the worst month at 63.6% on time, 15 points below February, the best at 78.9%. Summer afternoon convection and peak-season schedules land on the same weeks every year, so this is a pattern you can book around rather than a run of bad luck. July was the busiest month here, with 28,959 flights.
Across the week, Tuesday is the strongest day at 76.7% on time and Sunday the weakest at 66.7%. 10 points is a smaller lever than departure hour, but it is free.
Delay causes
Why DFW gets delayed
One category carries most of the weight here. Late-arriving aircraft accounts for 46% of the 6.26 million 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.
- 46%Late-arriving aircraft
- 31%Carrier
- 14%National Airspace System
- 9%Extreme weather
- 0%Security
46% 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 6.26 million reported delay minutes here, that single category outweighs weather by 5 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 6,264,616 reported delay minutes.
The practical consequence: the 5am–8am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 84.5% on time here.
Cancellations run at 2.97%, against 1.81% nationally. That is roughly one flight in 30 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. 10.8% of arrivals land a full hour or more behind schedule, against 8.1% 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.
312,851 flights sit behind these numbers, which is a large enough sample that the headline rate is not moving on noise. Where a sub-group falls below 30 flights the site shows a dash instead of a percentage.
What to do with this
Flying out of DFW
Put together: the delay figures matter less here than the 2.97% cancellation rate. A late arrival costs you a little over an hour; a cancelled flight costs you the day. Book the 5am–8am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 302,634 completed flights over 12 months sit behind that.
Common questions
DFW delay questions
How often is Dallas-Fort Worth (DFW) delayed?
Roughly one flight in four arrive at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 28.0% of the 312,851 flights in this analysis, against 22.4% nationally. Delayed flights are late by a little over an hour on average.
Which airline is most reliable on Dallas-Fort Worth (DFW)?
Envoy Air leads at 82.1% on time across 63,918 flights. American Airlines is at the other end on 65.9%, a gap of 16 points. Sample size matters as much as the percentage: a rate built from a few hundred flights moves around far more than one built from ten thousand.
What time of day has the fewest delays on Dallas-Fort Worth (DFW)?
The 5am–8am departure window is the strongest at 84.5% on time. The 5pm–8pm window is the weakest at 63.8%, 21 points behind. Later departures inherit delays from earlier flights the same aircraft has already flown, which is why the curve slopes the way it does.
How bad are June delays on Dallas-Fort Worth (DFW)?
June is the weakest month at 63.6% on time, compared with 78.9% in February. Across the year that is 15 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
