Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with Frontier Airlines.

Frontier on JFK to DFW lands a B, level with the national rate of 77.6%. Roughly one flight in four arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That is a workable record, not a spotless one. That rests on 171 flights. The strongest carrier on the route with a full sample, American Airlines, flew 1,409 at 77.6% on time.

The US average over the same twelve months is 77.6%, so there is little to separate Frontier on JFK to DFW from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Every carrier on JFK to DFW, 2,014 flights

These figures cover 171 flights between July 2025 and June 2026. The median arrival is 11 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 JFK to DFW

Frontier flew 171 of the 2,014 flights on JFK to DFW, about 8% of it. Its 77.5% on time is about level with the route as a whole at 76.3%. Ranked by on-time rate it is number two of three carriers on the route, where the range runs from American at 77.6% to Delta at 71.2%.

The choice of carrier is not cosmetic here. American Airlines arrives on time 77.6% of the time; Delta Air Lines manages 71.2%. Sample sizes sit next to every figure, because a two-point gap across 434 flights means less than a ten-point one.

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 JFK to DFW record by time of day without the percentages moving on noise. The headline rate of 77.5% is the reliable figure here.

Across the year

Frontier on JFK to DFW through the year

Jul–Sep 202591 flights73.3%
Oct–Dec 202575 flights81.1%
Jan–Mar 20265 flights—

Scale runs 65% to 85%. 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 77.5% on time across 171 flights.

Split by quarter, Frontier on JFK to DFW 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 77.5% annual figure is the one to use.

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 2,586 reported delay minutes.

National Airspace System
32%
Carrier
31%
Extreme weather
27%
Late-arriving aircraft
11%

Extreme weather accounts for 27% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the monthly strip above is the more useful view of the risk. The national share is 6%, so this operation carries roughly 4.3 times the usual weather exposure. The split is drawn from 2,586 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

6.5% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last a little over an hour, which a normal layover absorbs.

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 87.0% on time across 171 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. 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 JFK to DFW

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 77.5% 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.
