Historical statistics for July 2025 to June 2026, not live status. For today’s AS 773, check with Alaska Airlines.

AS 773 earns an A+. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 9 points better than the national rate of 77.6%. When something does go wrong the average delay runs roughly 50 minutes. That rests on 316 flights, with a median arrival 10 minutes early.

Set against the rest of the country, AS 773's record is 9 points better than the US average of 77.6%. That gap is worth roughly 87 fewer late arrivals for every thousand flights.

These figures cover 316 flights between July 2025 and June 2026. The median arrival is 10 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 773 flies

AS 773 flies SEA to SNA without a single fixed slot. Its most common scheduled departure was 14:10, used on 48 of 316 flights, with 13:29 (36 flights) and 16:18 (33 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 14:10 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and AS 773 runs 14 points better at 86.3%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

AS 773 quarter by quarter

AS 773 did not run the same all year. Its best quarter was Apr–Jun 2026 at 91.1% on time and its weakest Jul–Sep 2025 at 80.6%, a swing of 11 points on roughly 79 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.

Jan–Mar 202688 flights87.4%

Scale runs 70% to 95%. Rows with fewer than 30 flights show a dash.

By weekday, AS 773 ranged from 82.9% on Saturday to 90.0% on Wednesday. With about 45 flights behind each day, a spread of 7 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why AS 773 runs late

One category carries most of the weight here. Carrier accounts for 56% of the 2,092 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.

Carrier
56%
Late-arriving aircraft
32%
National Airspace System
12%

The largest share of delay minutes, 56%, 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 1,180 of the 2,092 delay minutes reported here. The split is drawn from 2,092 delay minutes reported on AS 773.

Cancellations are rare at 0.32%, below the national 1.81% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 2.5% 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.

The 978 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.

Every one of the 316 flights under AS 773 in the data flew SEA to SNA. 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. 316 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 773

For a booking, AS 773 has one of the better records a US domestic flight can show: 86.3% on time and 0.32% cancelled. That is a base rate, not a promise about any single day.
