Every carrier on DFW to JFK, 1,948 flights

These figures cover 109 flights between September 2025 and August 2026. The median arrival is 15 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 109 of the 1,948 flights on DFW to JFK, about 6% of it. Its 93.5% on time is 19 points better than the route as a whole, which runs 74.6%. Ranked by on-time rate it is first of three carriers on the route, where the range runs from Frontier at 93.5% to American at 69.4%.

The choice of carrier is not cosmetic here. Delta Air Lines arrives on time 89.9% of the time; American Airlines manages 69.4%. Sample sizes sit next to every figure, because a two-point gap across 1,466 flights means less than a ten-point one.

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 109 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 93.5% is the reliable figure here.

Across the year

Frontier on DFW to JFK through the year

  • Jul–Sep 202529 flights—
  • Oct–Dec 202575 flights97.3%
  • Jan–Mar 20265 flights—

Scale runs 90% 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 93.5% on time across 109 flights.

Split by quarter, Frontier on DFW to JFK logged 29 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 93.5% 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 304 reported delay minutes.

  • Carrier
    41%
  • National Airspace System
    35%
  • Late-arriving aircraft
    19%
  • Extreme weather
    5%

The largest share of delay minutes, 41%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 126 of the 304 delay minutes reported here. The split is drawn from 304 reported delay minutes.

35% 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 105 minutes out of 304, against a national NAS share of 21%.

Cancellations sit at 0.92% against a national 1.89%, which is ordinary. Diversions add another 0.00%.

Connections and stage length

What a delay here costs

Badly late arrivals are rare here: only 2.8% land an hour or more behind schedule, against 8.3% 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.

The return leg is a different operation and performs like one: it runs 83.3% on time across 109 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. 109 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. 109 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 93.5% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 108 completed flights over 12 months sit behind that.
