The choice of carrier is not cosmetic here. Delta Air Lines arrives on time 78.4% of the time; JetBlue Airways manages 68.6%. Sample sizes sit next to every figure, because a two-point gap across 1,114 flights means less than a ten-point one.

Delay causes
Why Frontier runs late on this route
Late-arriving aircraft accounts for 52% of the 16,000 delay minutes carriers reported here, and the remaining four split what is left.
- 52%Late-arriving aircraft
- 33%Carrier
- 11%National Airspace System
- 4%Extreme weather
52% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 16,000 reported delay minutes here, that single category outweighs weather by 13 to one. The split is drawn from 15,522 reported delay minutes.
The practical consequence: the 5am–8am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 76.3% on time here.
Cancellations sit at 2.28% against a national 1.89%, which is ordinary. Diversions add another 0.15%.
Connections and stage length
What a delay here costs
11.5% 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 760 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 68.6% on time across 661 flights, within 2 points 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. 659 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 ATL to JFK
Put together: treat all of this as provisional. 659 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 70.1% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 643 completed flights over 12 months sit behind that.
