CGRADE

Frontier Airlines at Dallas-Fort Worth sits in the middle of the pack with a C. Close to three flights in four arrive on time by the DOT's definition, 3 points worse than the national rate of 77.6%. The late ones land a little over an hour behind schedule. That rests on 9,912 flights, of which Envoy Air flew 63,918 at 82.1% on time.

Measured against the airport rather than the country, Frontier Airlines runs 3 points ahead of the 72.0% 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 9,912 flights between July 2025 and June 2026. Beyond the headline rate, 10.1% 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 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.

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–8am1,769 flights84.7%
  • 8am–11am1,534 flights82.8%
  • 11am–2pm1,578 flights77.3%
  • 2pm–5pm1,744 flights71.1%
  • 5pm–8pm1,351 flights67.3%
  • 8pm–5am1,936 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 84.7% 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. The 8pm–5am window is the busiest, with 1,936 flights scheduled in it.

Darker means more delays. Figures are on-time percentages.February best, June worst

June is the worst month at 65.1% on time, 20 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. June was the busiest month here, with 1,135 flights.

Delay causes

What holds this operation up

  • Late-arriving aircraft
    57%
  • National Airspace System
    21%
  • Carrier
    18%
  • Extreme weather
    3%

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 196,000 reported delay minutes here, that single category outweighs weather by 17 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 196,351 reported delay minutes.

Cancellations sit at 2.14% against a national 1.81%, which is ordinary. Diversions add another 0.21%.

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 10.1% 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.

The sample behind these figures is 9,912 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 65.1%, a swing of 20 points. If the dates move at all, move them out of June before you think about anything else. 9,679 completed flights over 12 months sit behind that.

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 25.3% of the 9,912 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 Frontier Airlines at 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 Frontier Airlines at DFW?

The 5am–8am departure window is the strongest at 84.7% 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 65.1% on time, compared with 85.4% in February. Across the year that is 20 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
