Carrier by carrier
Frontier against every carrier on EWR to ATL
Frontier flew 708 of the 6,252 flights on EWR to ATL, about 11% of it. Its 70.8% on time is 6 points worse than the route as a whole, which runs 76.9%. Ranked by on-time rate it is number four of five carriers on the route, where the range runs from Republic at 86.1% to Spirit at 70.1%. Two of those carriers flew fewer than 365 flights here, so treat their positions as rough.
The two carriers here are closely matched: 3 points separate the best from the worst. At that spread, schedule and price are better tie-breakers than reliability. Sample sizes are shown so you can see which rows are worth weighing.

Delta Air Lines cancels 4.0% 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 17 points, against 3 points between the best and worst carrier.
- 5am–8am363 flights77.0%
- 8am–11am—
- 11am–2pm87 flights76.5%
- 2pm–5pm—
- 5pm–8pm—
- 8pm–5am258 flights59.6%
Scale runs 50% to 80%. Rows with fewer than 30 flights show a dash.
The 8pm–5am window is where this operation falls apart: 59.6% on time, against 77.0% for the 5am–8am 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 5am–8am window is the busiest, with 363 flights scheduled in it.
Across the year
Frontier on EWR to ATL through the year
December is the weak month at 55.4% on time, against 93.4% in May. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days. May was the busiest month here, with 62 flights.
Across the week, Thursday is the strongest day at 77.6% on time and Sunday the weakest at 58.1%, a spread of 19 points.

Share of 672 completed flights by arrival against schedule.
29 of 153 late departures made up the time and arrived on time, 19% of them. In the other direction, 72 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at ATL.
The worst days
Worst days for Frontier on EWR to ATL
The latest arrival of the period was on 7 August 2026, 18 hours 31 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on four of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 7 August 2026 | 18 hours 31 minutes | Late-arriving aircraft |
| 31 December 2025 | 18 hours 3 minutes | Carrier |
| 15 July 2026 | 15 hours 55 minutes | Late-arriving aircraft |
| 11 March 2026 | 9 hours 43 minutes | Late-arriving aircraft |
| 13 December 2025 | 6 hours 50 minutes | Late-arriving aircraft |
Delay causes
Why Frontier runs late on this route
Late-arriving aircraft accounts for 60% of the 19,000 delay minutes carriers reported here, and the remaining four split what is left.
- 60%Late-arriving aircraft
- 20%Carrier
- 18%National Airspace System
- 2%Extreme weather
60% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 19,000 reported delay minutes here, that single category outweighs weather by 39 to one. The split is drawn from 18,531 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 77.0% on time here.
Cancellations run at 4.66%, against 1.89% nationally. That is about 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
13.5% 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 746 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 58.5% on time across 707 flights, 12 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 12 points of difference.
One caution: this is a thin sample. 708 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 EWR to ATL
Put together: the delay figures matter less here than the 4.66% cancellation rate. A late arrival costs you an hour and a half; a cancelled flight costs you the day. Book the 5am–8am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 672 completed flights over 12 months sit behind that.
