Frontier on DFW to JFK earns an A. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 9 points better than the national rate of 77.6%. When something does go wrong the average delay runs roughly 30 minutes. That rests on 171 flights. The strongest carrier on the route with a full sample, Delta Air Lines, flew 434 at 88.8% on time.

Set against the rest of the country, Frontier's DFW to JFK record is 9 points better than the US average of 77.6%. That gap is worth roughly 94 fewer late arrivals for every thousand flights.

Every carrier on DFW to JFK, 2,009 flights

These figures cover 171 flights between July 2025 and June 2026. The median arrival is 8 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Carrier by carrier

Frontier against every carrier on DFW to JFK

Frontier flew 171 of the 2,009 flights on DFW to JFK, about 9% of it. Its 87.0% on time is 10 points better than the route as a whole, which runs 77.0%. Ranked by on-time rate it is number two of three carriers on the route, where the range runs from Delta at 88.8% to American at 72.3%.

The choice of carrier is not cosmetic here. Delta Air Lines arrives on time 88.8% of the time; American Airlines manages 72.3%. Sample sizes sit next to every figure, because a two-point gap across 1,404 flights means less than a ten-point one.

On-time performance by carrier on DFW to JFK
Airline	Flights	On time	Avg delay	Cancelled	Grade
Delta Air Lines	434	88.8%	75 min	4.84%	A−

Delta Air Lines 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 is the single lever a traveller controls, and it moves the odds more than most people expect. Each bar below is the on-time rate for flights scheduled to leave inside that window, across 171 flights.

There are not enough flights in each departure window to split Frontier's DFW to JFK record by time of day without the percentages moving on noise. The headline rate of 87.0% is the reliable figure here.

Across the year

Frontier on DFW to JFK through the year

Jul–Sep 202591 flights77.8%
Oct–Dec 202575 flights97.3%
Jan–Mar 20265 flights—

Scale runs 70% to 100%. Rows with fewer than 30 flights show a dash.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 87.0% on time across 171 flights.

Split by quarter, Frontier on DFW to JFK logged 91 flights in Jul–Sep 2025, 75 flights in Oct–Dec 2025 and 5 flights in Jan–Mar 2026. Fewer than three of those quarters carried the 30 completed flights this site needs before printing a rate, so the 87.0% annual figure is the one to use.

Delay causes

Why Frontier runs late on this route

One category carries most of the weight here. National Airspace System accounts for 46% of the 686 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.

National Airspace System
46%
Carrier
31%
Late-arriving aircraft
21%
Extreme weather
2%

46% 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 317 minutes out of 686, against a national NAS share of 21%. The split is drawn from 686 reported delay minutes.

Cancellations sit at 1.17% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and stage length

What a delay here costs

Badly late arrivals are rare here: only 1.8% land an hour or more behind schedule, against 8.1% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.

The 1,391 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 77.5% on time across 171 flights, 10 points below 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. 171 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 JFK

Put together: treat all of this as provisional. 171 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 87.0% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 169 completed flights over 12 months sit behind that.
