Carrier by carrier
Frontier against every carrier on FLL to DFW
Frontier flew 205 of the 3,149 flights on FLL to DFW, about 7% of it. Its 57.1% on time is 15 points worse than the route as a whole, which runs 72.1%. Ranked by on-time rate it is last of four carriers on the route, where the range runs from American at 74.0% to Frontier at 57.1%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.
The two carriers here are closely matched: 3 points separate the best from the worst. At that spread, schedule and price are better tie-breakers than reliability. Sample sizes are shown so you can see which rows are worth weighing.

Spirit Airlines cancels 3.5% 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
When Frontier runs best on this route

The 5pm–8pm window is where this operation falls apart: 44.6% on time, against 76.3% for the 11am–2pm 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 76 flights scheduled in it.

Share of 196 completed flights by arrival against schedule.
18 of 78 late departures made up the time and arrived on time, 23% of them. In the other direction, 24 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 FLL to DFW
The latest arrival of the period was on 25 March 2026, 12 hours 2 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 25 March 2026 | 12 hours 2 minutes | Carrier |
| 20 November 2025 | 5 hours 17 minutes | National Airspace System |
| 10 May 2026 | 3 hours 31 minutes | National Airspace System |

Delay causes
Why Frontier runs late on this route
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 5,582 reported delay minutes.
- 35%Late-arriving aircraft
- 32%National Airspace System
- 31%Carrier
- 1%Extreme weather
35% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 5,582 reported delay minutes here, that single category outweighs weather by 30 to one. The split is drawn from 5,582 reported delay minutes.
32% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 1,795 minutes out of 5,582, against a national NAS share of 21%.
Cancellations run at 3.41%, against 1.89% nationally. That is about 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.
Connections and stage length
What a delay here costs
14.8% 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 1,119 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 67.5% on time across 205 flights, 10 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 10 points of difference.
One caution: this is a thin sample. 205 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 FLL to DFW
Put together: the delay figures matter less here than the 3.41% cancellation rate. A late arrival costs you about an hour; a cancelled flight costs you the day. Book the 11am–2pm departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 196 completed flights over 12 months sit behind that.
