Historical statistics for July 2025 to June 2026, not live status. For today’s AS 35, check with Alaska Airlines.

AS 35 lands a B, 2 points worse than the national rate of 77.6%. About one flight in four arrives 15 minutes late or worse, and those flights are late by about an hour on average. That is a workable record, not a spotless one. That rests on 266 flights, with a median arrival 1 minute early.

These figures cover 266 flights between July 2025 and June 2026. On-time means an arrival less than 15 minutes after the scheduled gate time, the same threshold the Department of Transportation uses in its own reports. Cancelled and diverted flights are excluded from the on-time rate and counted separately, which is why the cancellation column matters on its own.

Schedule

When AS 35 flies

AS 35 flies JFK to SAN without a single fixed slot. Its most common scheduled departure was 10:00, used on 117 of 266 flights, with 09:30 (107 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 10:00 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and AS 35 runs 8 points worse at 76.0%. 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 35 quarter by quarter

AS 35 did not run the same all year. Its best quarter was Apr–Jun 2026 at 84.1% on time and its weakest Oct–Dec 2025 at 70.3%, a swing of 14 points on roughly 89 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.

By weekday, AS 35 did best on Tuesday at 86.8% on time and worst on Sunday at 62.2%. Each day rests on about 38 flights, so a gap of 25 points is worth noticing but could still narrow in another year.

Delay causes

Why AS 35 runs late

One category carries most of the weight here. Carrier accounts for 53% of the 3,912 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.

The largest share of delay minutes, 53%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 2,077 of the 3,912 delay minutes reported here. The split is drawn from 3,912 delay minutes reported on AS 35.

Cancellations sit at 1.50% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

6.1% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.

At 2,446 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.

Every one of the 266 flights under AS 35 in the data flew JFK to SAN. The number was not reused on any other city pair, which makes this a clean record of one route.

One caution: this is a thin sample. 266 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 35
