Alaska on LAX to EWR earns an A. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 14 points better than the national rate of 77.3%. When something does go wrong the average delay runs about an hour. That rests on 490 flights. The strongest carrier on the route with a full sample, JetBlue Airways, flew 480 at 78.4% on time.
Set against the rest of the country, Alaska's LAX to EWR record is 14 points better than the US average of 77.3%. That gap is worth roughly 143 fewer late arrivals for every thousand flights.

Every carrier on LAX to EWR, 4,748 flights
These figures cover 490 flights between September 2025 and August 2026. The median arrival is 21 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Carrier by carrier
Alaska against every carrier on LAX to EWR
Alaska flew 490 of the 4,748 flights on LAX to EWR, about 10% of it. Its 91.6% on time is 13 points better than the route as a whole, which runs 79.1%. Ranked by on-time rate it is first of four carriers on the route, where the range runs from Alaska at 91.6% to Spirit at 75.1%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.
The two carriers here are closely matched: half a point 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.

| Alaska Airlines (this page) | 490 | 91.6% | 58 min | 1.63% | A |

JetBlue Airways cancels 3.5% 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 Alaska runs best on this route
Departure time is the single lever a traveller controls, and it moves the odds more than most people expect. Each bar below is the on-time rate for flights scheduled to leave inside that window, across 490 flights.
- 5am–8am215 flights93.8%
- 8am–11am148 flights87.8%
- 11am–2pm—
- 2pm–5pm—
- 5pm–8pm—
- 8pm–5am127 flights92.1%
Scale runs 80% to 100%. Rows with fewer than 30 flights show a dash.
The early departures do better, though not dramatically: 93.8% on time for the 5am–8am window against 87.8% for 8am–11am. Worth taking if the schedule allows, not worth an extra connection. The 5am–8am window is the busiest, with 215 flights scheduled in it.
Across the year
Alaska on LAX to EWR through the year
January is the weak month at 82.9% on time, against 100.0% in March. 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. October was the busiest month here, with 62 flights.
Across the week, Tuesday is the strongest day at 95.6% on time and Sunday the weakest at 86.6%, a spread of 9 points.
Arrival by arrival
How late Alaska on LAX to EWR runs when it is late

A late pushback is often recovered here: of 58 departures that left 15 minutes late or more, 24 still arrived on time. Only 6 left on time and still arrived late.
The worst days
Worst days for Alaska on LAX to EWR
The latest arrival of the period was on 2 November 2025, 4 hours 52 minutes behind schedule; most of its delay minutes were filed as national airspace system delay. The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 2 November 2025 | 4 hours 52 minutes | National Airspace System |
| 9 November 2025 | 3 hours 23 minutes | National Airspace System |
| 3 August 2026 | 2 hours 56 minutes | National Airspace System |
| 27 December 2025 | 2 hours 11 minutes | Late-arriving aircraft |
| 21 August 2026 | 1 hour 51 minutes | Carrier |
Delay causes
Why Alaska runs late on this route
National Airspace System accounts for 46% of the 2,309 delay minutes carriers reported here, and the remaining four split what is left.
- 46%National Airspace System
- 44%Carrier
- 10%Late-arriving aircraft
The largest share of delay minutes, 44%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,018 of the 2,309 delay minutes reported here. The split is drawn from 2,309 reported delay minutes.
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 1,052 minutes out of 2,309, against a national NAS share of 21%.
Cancellations sit at 1.63% against a national 1.89%, which is ordinary. Diversions add another 1.02%.
Connections and stage length
What a delay here costs
Badly late arrivals are rare here: only 2.5% land an hour or more behind schedule, against 8.3% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
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 72.1% on time across 491 flights, 20 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 20 points of difference.
One caution: this is a thin sample. 490 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 Alaska on LAX to EWR
Put together: treat all of this as provisional. 490 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 91.6% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 477 completed flights over 12 months sit behind that.
