Carrier by carrier
Frontier against every carrier on LAX to DFW
Frontier flew 510 of the 6,178 flights on LAX to DFW, about 8% of it. Its 72.6% on time is 2 points worse than the route as a whole, which runs 74.9%. Ranked by on-time rate it is number three of four carriers on the route, where the range runs from Delta at 85.4% to Spirit at 70.8%.
The choice of carrier is not cosmetic here. Delta Air Lines arrives on time 85.4% of the time; Spirit Airlines manages 70.8%. Sample sizes sit next to every figure, because a two-point gap across 383 flights means less than a ten-point one.

|---|---|---|---|---|---|
| Delta Air Lines | 757 | 85.4% | 75 min | 1.45% | A |

20 of 113 late departures made up the time and arrived on time, 18% of them. In the other direction, 43 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at DFW.
The worst days
Worst days for Frontier on LAX to DFW
The latest arrival of the period was on 27 October 2025, 19 hours 25 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 27 October 2025 | 19 hours 25 minutes | Late-arriving aircraft |
| 29 September 2025 | 13 hours 21 minutes | Late-arriving aircraft |
| 25 January 2026 | 13 hours 19 minutes | Carrier |

Delay causes
Why Frontier runs late on this route
Late-arriving aircraft accounts for 55% of the 12,000 delay minutes carriers reported here, and the remaining four split what is left.
- 55%Late-arriving aircraft
- 29%Carrier
- 15%National Airspace System
- 1%Extreme weather
55% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 12,000 reported delay minutes here, that single category outweighs weather by 55 to one. The split is drawn from 12,016 reported delay minutes.
The practical consequence: the 8am–11am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 82.3% on time here.
Cancellations sit at 1.76% against a national 1.89%, which is ordinary. Diversions add another 0.78%.
Connections and stage length
What a delay here costs
9.5% 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 1,235 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
The return leg is a different operation and performs like one: it runs 79.2% on time across 510 flights, 7 points above this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 7 points of difference.
One caution: this is a thin sample. 510 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.
What to do with this
Booking Frontier on LAX to DFW
Put together: treat all of this as provisional. 510 flights over twelve months is enough to clear this site's floor and not enough to be confident to better than a couple of points. The 72.6% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 497 completed flights over 12 months sit behind that.
