Carrier by carrier
Spirit against every carrier on ATL to EWR
Spirit flew 358 of the 6,246 flights on ATL to EWR, about 6% of it. Its 64.0% on time is 8 points worse than the route as a whole, which runs 72.3%. Ranked by on-time rate it is number four of five carriers on the route, where the range runs from Republic at 81.7% to Frontier at 58.5%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.
The choice of carrier is not cosmetic here. United Airlines arrives on time 79.0% of the time; Frontier Airlines manages 58.5%. Sample sizes sit next to every figure, because a two-point gap across 707 flights means less than a ten-point one.

Frontier Airlines cancels 4.2% 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 Spirit runs best on this route
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 41 points, against 21 points between the best and worst carrier.

- 8am–11am15 flights—

Scale runs 30% to 85%. Rows with fewer than 30 flights show a dash.
The 8pm–5am window is where this operation falls apart: 40.7% on time, against 81.8% 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 161 flights scheduled in it.

Delay causes
Why Spirit 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 8,532 reported delay minutes.
- 39%Carrier
- 31%National Airspace System
- 29%Late-arriving aircraft
- 1%Security
The largest share of delay minutes, 39%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 3,363 of the 8,532 delay minutes reported here. The split is drawn from 8,532 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 81.8% on time here.
Cancellations run at 7.54%, against 1.89% nationally. That is roughly one flight in twelve 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
15.7% 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 70.1% on time across 363 flights, 6 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 6 points of difference.
One caution: this is a thin sample. 358 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 Spirit on ATL to EWR
Put together: the delay figures matter less here than the 7.54% cancellation rate. A late arrival costs you a little over an hour; 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. 331 completed flights over 12 months sit behind that.
