AS 22 lands a B+, 7 points better than the national rate of 77.3%. About one flight in six arrives 15 minutes late or worse, and those flights are late by roughly 35 minutes on average. That rests on 315 flights, with a median arrival 9 minutes early.

These figures cover 315 flights between September 2025 and August 2026. The median arrival is 9 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 22 quarter by quarter

The worst days
Worst days for AS 22
The latest arrival of the period was on 29 September 2025, 2 hours 42 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 29 September 2025 | 2 hours 42 minutes | Late-arriving aircraft |
| 15 March 2026 | 1 hour 47 minutes | Late-arriving aircraft |
| 5 August 2026 | 1 hour 21 minutes | Late-arriving aircraft |
| 15 May 2026 | 1 hour 20 minutes | Carrier |

Delay causes
Why AS 22 runs late
Late-arriving aircraft accounts for 57% of the 1,823 delay minutes carriers reported here, and the remaining four split what is left.
- 57%Late-arriving aircraft
- 29%Carrier
- 14%National Airspace System
57% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 1,823 reported delay minutes here, that single category outweighs weather by 57 to one. The split is drawn from 1,823 delay minutes reported on AS 22.
Cancellations are rare at 0.63%, 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 2.9% 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 2,422 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 315 flights under AS 22 in the data flew SEA to JFK. 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. 315 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 22
For a booking, read AS 22 as 83.9% on time with 0.63% cancelled over 315 flights. Those are rates from the past twelve months, not a forecast for any particular day.
