Carrier by carrier
Frontier against every carrier on DFW to LGA
Frontier flew 292 of the 6,650 flights on DFW to LGA, about 4% of it. Its 58.7% on time is 7 points worse than the route as a whole, which runs 66.1%. Ranked by on-time rate it is last of four carriers on the route, where the range runs from Delta at 72.5% to Frontier at 58.7%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.
The choice of carrier is not cosmetic here. Delta Air Lines arrives on time 72.5% of the time; American Airlines manages 64.0%. Sample sizes sit next to every figure, because a two-point gap across 4,311 flights means less than a ten-point one.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| Delta Air Lines | 1,851 | 72.5% | 92 min | 5.24% | C− |
| American Airlines | 4,311 | 64.0% | 70 min | 4.80% | D− |

| Frontier Airlines (this page)thin sample | 292 | 58.7% | 77 min | 6.51% | D− |
Delta Air Lines cancels 5.2% 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.

Share of 271 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 103 departures that left 15 minutes late or more, only 12 made it up before arrival. In the other direction, 21 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 LGA.

Worst days for Frontier on DFW to LGA
The latest arrival of the period was on 11 November 2025, 5 hours 34 minutes behind schedule; most of its delay minutes were filed as national airspace system delay. Three of the five worst days fell in November 2025.

Delay causes
Why Frontier runs late on this route
National Airspace System accounts for 63% of the 8,658 delay minutes carriers reported here, and the remaining four split what is left.
- 63%National Airspace System
- 20%Late-arriving aircraft
- 13%Carrier
- 4%Extreme weather
63% 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 5,453 minutes out of 8,658, against a national NAS share of 21%. The split is drawn from 8,658 reported delay minutes.
Cancellations run at 6.51%, against 1.89% nationally. That is about one flight in fifteen 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
19.9% 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 1,389 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 runs 59.3% on time across 291 flights, within half a point of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.
One caution: this is a thin sample. 292 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 DFW to LGA
Put together: the delay figures matter less here than the 6.51% cancellation rate. A late arrival costs you a little over an hour; a cancelled flight costs you the day. Book the 2pm–5pm departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 271 completed flights over 12 months sit behind that.
