Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with Frontier Airlines.
Frontier on DFW to LGA draws a D−. Roughly one flight in three arrives at least 15 minutes late, and the typical late arrival is a little over an hour behind schedule. Build slack into anything you connect to. That rests on 291 flights. The strongest carrier on the route with a full sample, Delta Air Lines, flew 1,955 at 73.4% on time.
The national on-time rate over the same period is 77.6%, so Frontier on DFW to LGA runs 15 points behind the country as a whole. Across a thousand flights that is about 150 extra late arrivals.

These figures cover 291 flights between July 2025 and June 2026. Beyond the headline rate, 17.6% 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.
Carrier by carrier
Frontier against every carrier on DFW to LGA
Frontier flew 291 of the 6,786 flights on DFW to LGA, about 4% of it. Its 62.6% on time is 4 points worse than the route as a whole, which runs 67.1%. Ranked by on-time rate it is last of four carriers on the route, where the range runs from Delta at 73.4% to Frontier at 62.6%. 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 73.4% of the time; American Airlines manages 64.6%. Sample sizes sit next to every figure, because a two-point gap across 4,298 flights means less than a ten-point one.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| Delta Air Lines | 1,955 | 73.4% | 96 min | 4.55% | C− |
| Spirit Airlinesthin sample | 242 | 65.8% | 75 min | 5.79% | C− |
| American Airlines | 4,298 | 64.6% | 70 min | 4.84% | D− |
| Frontier Airlines (this page)thin sample | 291 | 62.6% | 77 min | 5.50% | D− |
American Airlines cancels 4.8% 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
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 14 points, against 9 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

- 11am–2pm—
- 2pm–5pm211 flights65.7%
- 5pm–8pm76 flights51.5%

Scale runs 45% to 70%. Rows with fewer than 30 flights show a dash.
The 5pm–8pm window is where this operation falls apart: 51.5% on time, against 65.7% for the 2pm–5pm 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 2pm–5pm window is the busiest, with 211 flights scheduled in it.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 62.6% on time across 291 flights.
Frontier on DFW to LGA did not run the same all year. Its best quarter was Jul–Sep 2025 at 69.8% on time and its weakest Apr–Jun 2026 at 55.3%, a swing of 15 points on roughly 73 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.
Across the week, Saturday is the strongest day at 77.8% on time and Sunday the weakest at 48.6%. 29 points is a smaller lever than departure hour, but it is free.
Delay causes
Why Frontier runs late on this route
One category carries most of the weight here. National Airspace System accounts for 65% of the 7,836 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.
- 65%National Airspace System
- 18%Late-arriving aircraft
- 12%Carrier
- 5%Extreme weather
65% 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 5,067 minutes out of 7,836, against a national NAS share of 21%. The split is drawn from 7,836 reported delay minutes.
Cancellations run at 5.50%, against 1.81% nationally. That is roughly one flight in twenty 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
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 17.6% 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 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
The return leg is a different operation and performs like one: it runs 66.2% on time across 291 flights, 4 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 4 points of difference.
One caution: this is a thin sample. 291 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 5.50% 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. 273 completed flights over 12 months sit behind that.
