United Airlines at Dallas-Fort Worth lands a B, level with the national rate of 77.3%. About one flight in four arrives 15 minutes late or worse, and those flights are late by an hour and a half on average. That rests on 10,062 flights, of which Envoy Air flew 64,201 at 83.6% on time.
Measured against the airport rather than the country, United Airlines runs 4 points ahead of the 72.8% weighted average across all carriers at DFW. That is the comparison worth making: every operator here works the same runways, the same airspace and the same weather.

Against the competition
Every carrier at DFW, ranked
The choice of carrier is not cosmetic here. Envoy Air arrives on time 83.6% of the time; American Airlines manages 66.7%. Sample sizes sit next to every figure, because a two-point gap across 164,984 flights means less than a ten-point one.

| American Airlines | 164,984 | 66.7% | 73 min | 2.68% | C |
PSA Airlines cancels 4.3% 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.
Route by route
Where United Airlines flies from DFW
United Airlines operates 6 routes out of DFW with enough volume to report. Route records inside one carrier at one airport still spread widely, because a short shuttle and a transcontinental have very different exposure to a late inbound.

Departure window
Best time of day for this operation
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 29 points, against 17 points between the best and worst carrier.
- 5am–8am2,366 flights88.0%
- 8am–11am1,310 flights81.5%
- 11am–2pm2,192 flights77.8%
- 2pm–5pm1,549 flights69.8%
- 5pm–8pm2,369 flights68.0%
- 8pm–5am276 flights58.7%
Scale runs 50% to 95%.
The 8pm–5am window is where this operation falls apart: 58.7% on time, against 88.0% 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 5pm–8pm window is the busiest, with 2,369 flights scheduled in it.
Across the year
Seasonal pattern
June is the worst month at 67.9% on time, 18 points below February, the best at 86.2%. 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 937 flights.
Delay causes
What holds this operation up
- 39%Late-arriving aircraft
- 38%National Airspace System
- 20%Carrier
- 3%Extreme weather
39% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 198,000 reported delay minutes here, that single category outweighs weather by 16 to one. The split is drawn from 197,561 reported delay minutes.
Cancellations sit at 1.62% against a national 1.89%, which is ordinary. Diversions add another 0.40%.
9.8% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
The sample behind these figures is 10,062 flights, enough that the headline rate is stable to within roughly a point. The hour-block and month splits divide that further, so read the thinner bars with more caution than the headline.
Put together: the calendar is the biggest lever here, not the carrier or the hour. February runs 86.2% on time and June 67.9%, a swing of 18 points. If the dates move at all, move them out of June before you think about anything else. 9,859 completed flights over 12 months sit behind that.
Common questions
United Airlines at DFW
How often is United Airlines at DFW delayed?
About one flight in four arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 23.4% of the 10,062 flights in this analysis, against 22.7% nationally. Delayed flights are late by an hour and a half on average.
Which airline is most reliable on United Airlines at DFW?
Envoy Air leads at 83.6% on time across 64,201 flights. American Airlines is at the other end on 66.7%, a gap of 17 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 United Airlines at DFW?
The 5am–8am departure window is the strongest at 88.0% on time. The 8pm–5am window is the weakest at 58.7%, 29 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 United Airlines at DFW?
June is the weakest month at 67.9% on time, compared with 86.2% in February. Across the year that is 18 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
