These figures cover 323 flights between September 2025 and August 2026. The median arrival is 7 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.

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 2026 at 74.2%, a swing of 17 points on roughly 81 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 773 did best on Wednesday at 95.2% on time and worst on Thursday at 79.6%. Each day rests on about 46 flights, so a gap of 16 points is worth noticing but could still narrow in another year.

Worst days for AS 773
The latest arrival of the period was on 25 June 2026, 3 hours 42 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 25 June 2026 | 3 hours 42 minutes | Carrier |
| 13 February 2026 | 3 hours 24 minutes | Carrier |
| 7 January 2026 | 2 hours 55 minutes | Carrier |

Delay causes
Why AS 773 runs late
Carrier accounts for 56% of the 2,127 delay minutes carriers reported here, and the remaining four split what is left.
- 56%Carrier
- 28%Late-arriving aircraft
- 16%National Airspace System
The largest share of delay minutes, 56%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,182 of the 2,127 delay minutes reported here. The split is drawn from 2,127 delay minutes reported on AS 773.
Cancellations are rare at 0.31%, below the national 1.89% 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 2.2% 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.
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.
Every one of the 323 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. 323 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: 85.4% on time and 0.31% cancelled. That is a base rate, not a promise about any single day.
