Frontier Airlines at Dallas-Fort Worth sits in the middle of the pack with a B. Close to three flights in four arrive on time by the DOT's definition, 2 points worse than the national rate of 77.4%. The late ones land a little over an hour behind schedule. That rests on 9,482 flights, of which Envoy Air flew 63,507 at 81.7% on time.
Measured against the airport rather than the country, Frontier Airlines runs 3 points ahead of the 71.8% 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.

#5
Of 9 carriers clearing the floor at DFW
These figures cover 9,482 flights between June 2025 and May 2026. Beyond the headline rate, 9.7% 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.
Against the competition
Every carrier at DFW, ranked
The choice of carrier is not cosmetic here. Envoy Air arrives on time 81.7% of the time; American Airlines manages 66.0%. Sample sizes sit next to every figure, because a two-point gap across 164,554 flights means less than a ten-point one.

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 Frontier Airlines flies from DFW
Frontier Airlines operates 25 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 20 points, against 16 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am1,814 flights85.0%
- 8am–11am1,389 flights83.1%
- 11am–2pm1,435 flights78.0%
- 2pm–5pm1,723 flights71.8%
- 5pm–8pm1,299 flights68.4%
- 8pm–5am1,822 flights65.2%
Scale runs 55% to 90%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 85.0% of the time, against 65.2% for the overnight window. That is 20 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on.
Across the year
Seasonal pattern
June is the worst month at 66.8% on time, 19 points below February, the best at 85.4%. 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.
Delay causes
What holds this operation up
- 57%Late-arriving aircraft
- 21%National Airspace System
- 20%Carrier
- 3%Extreme weather
57% 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 180,000 reported delay minutes here, that single category outweighs weather by 22 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.
Cancellations sit at 2.20% against a national 1.80%, which is ordinary. Diversions add another 0.19%.
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 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.
The sample behind these figures is 9,482 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 85.4% on time and June 66.8%, a swing of 19 points. If the dates move at all, move them out of June before you think about anything else.
Common questions
Frontier Airlines at DFW
How often is Frontier Airlines at DFW delayed?
About 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 24.8% of the 9,482 flights in this analysis, against 22.6% nationally. Delayed flights are late by a little over an hour on average.
Which airline is most reliable on Frontier Airlines at DFW?
Envoy Air leads at 81.7% on time across 63,507 flights. American Airlines is at the other end on 66.0%, 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 Frontier Airlines at DFW?
The 5am–8am departure window is the strongest at 85.0% on time. The 8pm–5am window is the weakest at 65.2%, 20 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 Frontier Airlines at DFW?
June is the weakest month at 66.8% on time, compared with 85.4% in February. Across the year that is 19 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
