Historical statistics for July 2025 to June 2026, not live status. For today’s AS 284, check with Alaska Airlines.
AS 284 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 12 points better than the national rate of 77.6%. When something does go wrong the average delay runs a little over an hour. That rests on 263 flights, with a median arrival 21 minutes early.
Set against the rest of the country, AS 284's record is 12 points better than the US average of 77.6%. That gap is worth roughly 115 fewer late arrivals for every thousand flights.

These figures cover 263 flights between July 2025 and June 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.
Schedule
When AS 284 flies
AS 284 flies LAX to EWR without a single fixed slot. Its most common scheduled departure was 07:00, used on 138 of 263 flights, with 07:05 (37 flights) and 08:02 (36 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 07:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and AS 284 runs level with that at 89.1%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year
AS 284 quarter by quarter
Quarter by quarter AS 284 held fairly steady: 84.3% in Jul–Sep 2025, 89.2% in Oct–Dec 2025 and 91.8% in Jan–Mar 2026. A spread of 8 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

- Oct–Dec 202574 flights89.2%
- Jan–Mar 202676 flights91.8%

Scale runs 75% to 95%. Rows with fewer than 30 flights show a dash.
By weekday, AS 284 did best on Tuesday at 94.7% on time and worst on Sunday at 75.0%. Each day rests on about 38 flights, so a gap of 20 points is worth noticing but could still narrow in another year.
Delay causes
Why AS 284 runs late
One category carries most of the weight here. National Airspace System accounts for 64% of the 2,051 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.
- 64%National Airspace System
- 31%Carrier
- 5%Late-arriving aircraft
- 1%Extreme weather
64% 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 1,316 minutes out of 2,051, against a national NAS share of 21%. The split is drawn from 2,051 delay minutes reported on AS 284.
Cancellations sit at 1.14% against a national 1.81%, which is ordinary. Diversions add another 1.14%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 3.9% land an hour or more behind schedule, against 8.1% 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 same number turns up on one other city pair in the data, including SEA to FAI (49), but none flew often enough under AS 284 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to LAX to EWR only.
One caution: this is a thin sample. 263 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 AS 284
For a booking, AS 284 has one of the better records a US domestic flight can show: 89.1% on time and 1.14% cancelled. That is a base rate, not a promise about any single day.
