These figures cover 317 flights between July 2025 and June 2026. Beyond the headline rate, 9.0% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.
Carrier by carrier
Spirit against every carrier on LAX to EWR
Spirit flew 317 of the 4,925 flights on LAX to EWR, about 6% of it. Its 75.4% on time is 4 points worse than the route as a whole, which runs 79.6%. Ranked by on-time rate it is last of four carriers on the route, where the range runs from Alaska at 90.1% to Spirit at 75.4%.
The choice of carrier is not cosmetic here. Alaska Airlines arrives on time 90.1% of the time; JetBlue Airways manages 77.2%. Sample sizes sit next to every figure, because a two-point gap across 517 flights means less than a ten-point one.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| Alaska Airlines | 552 | 90.1% | 59 min | 1.09% | A |
| United Airlines | 3,539 | 78.7% | 79 min | 1.92% | B |
| JetBlue Airways | 517 | 77.2% | 82 min | 2.71% | B |
| Spirit Airlines (this page)thin sample | 317 | 75.4% | 56 min | 4.42% | B− |
The spread between Alaska and JetBlue is 13 points, wide enough that it should decide the booking. On a hundred trips that is 13 more arrivals inside the on-time window.
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 24 points, against 13 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am126 flights91.7%
- 8am–11am138 flights67.4%
- 11am–2pm10 flights—
- 2pm–5pm12 flights—

Scale runs 60% to 95%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 91.7% of the time, against 67.4% for the morning window. That is 24 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 8am–11am window is the busiest, with 138 flights scheduled in it.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 75.4% on time across 317 flights.
Spirit on LAX to EWR did not run the same all year. Its best quarter was Oct–Dec 2025 at 85.3% on time and its weakest Jan–Mar 2026 at 60.0%, a swing of 25 points on roughly 106 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.
Across the week, Wednesday is the strongest day at 83.3% on time and Sunday the weakest at 68.3%. 15 points is a smaller lever than departure hour, but it is free.
Delay causes
Why Spirit runs late on this route
One category carries most of the weight here. National Airspace System accounts for 65% of the 4,167 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.
- 65%National Airspace System
- 19%Carrier
- 16%Late-arriving aircraft
65% 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 2,692 minutes out of 4,167, against a national NAS share of 21%. The split is drawn from 4,167 reported delay minutes.
Cancellations run at 4.42%, against 1.81% nationally. That is roughly one flight in 25 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
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 9.0% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.
At 2,454 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.
The return leg is a different operation and performs like one: it runs 66.7% on time across 317 flights, 9 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 9 points of difference.
One caution: this is a thin sample. 317 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 LAX to EWR
Put together: the delay figures matter less here than the 4.42% cancellation rate. A late arrival costs you about 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. 301 completed flights over 12 months sit behind that.
