Carrier by carrier
Spirit against every carrier on EWR to LAX
Spirit flew 252 of the 4,750 flights on EWR to LAX, about 5% of it. Its 62.6% on time is 8 points worse than the route as a whole, which runs 70.7%. Ranked by on-time rate it is last of four carriers on the route, where the range runs from Alaska at 72.1% to Spirit at 62.6%.
The three carriers here are closely matched: 2 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.

JetBlue Airways cancels 3.3% 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 20 points, against 2 points between the best and worst carrier.

Scale runs 45% to 80%. Rows with fewer than 30 flights show a dash.
The 8pm–5am window is where this operation falls apart: 55.8% on time, against 76.1% for the 8am–11am 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 5pm–8pm window is the busiest, with 116 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 62.6% on time across 252 flights.
Split by quarter, Spirit on EWR to LAX logged 30 flights in Jul–Sep 2025, 100 flights in Oct–Dec 2025, 96 flights in Jan–Mar 2026 and 26 flights in Apr–Jun 2026. Fewer than three of those quarters carried the 30 completed flights this site needs before printing a rate, so the 62.6% annual figure is the one to use.
Across the week, Wednesday is the strongest day at 82.4% on time and Friday the weakest at 48.6%, a spread of 34 points.
Arrival by arrival
How late Spirit on EWR to LAX runs when it is late
Spirit on EWR to LAX often beats the schedule: 60 of 230 completed flights, 26%, arrived 15 minutes or more early. The 86 late arrivals split 16 under half an hour, 27 between 30 and 60 minutes, and 43 an hour or more.

Share of 230 completed flights by arrival against schedule.
20 of 94 late departures made up the time and arrived on time, 21% of them. In the other direction, 12 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 LAX.
The worst days
Worst days for Spirit on EWR to LAX
The latest arrival of the period was on 3 November 2025, 9 hours 23 minutes behind schedule; most of its delay minutes were filed as national airspace system delay. On three of the five worst days the largest share was filed as a late-arriving aircraft.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 3 November 2025 | 9 hours 23 minutes | National Airspace System |
| 6 September 2025 | 6 hours 32 minutes | Late-arriving aircraft |
| 20 December 2025 | 5 hours 27 minutes | Late-arriving aircraft |

Delay causes
Why Spirit runs late on this route
National Airspace System accounts for 46% of the 7,046 delay minutes carriers reported here, and the remaining four split what is left.
- 46%National Airspace System
- 30%Late-arriving aircraft
- 21%Carrier
- 2%Security
- 0%Extreme weather
46% 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 3,271 minutes out of 7,046, against a national NAS share of 21%. The split is drawn from 7,046 reported delay minutes.
The practical consequence: the 8am–11am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 76.1% on time here.
Cancellations run at 7.94%, against 1.89% nationally. That is about 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
18.7% 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.
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 75.1% on time across 252 flights, 12 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 12 points of difference.
One caution: this is a thin sample. 252 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 EWR to LAX
Put together: the delay figures matter less here than the 7.94% cancellation rate. A late arrival costs you a little over an hour; a cancelled flight costs you the day. Book the 8am–11am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 230 completed flights over 12 months sit behind that.
