These figures cover 361 flights between September 2025 and August 2026. The median arrival is 12 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 353 quarter by quarter
AS 353 did not run the same all year. Its best quarter was Apr–Jun 2026 at 94.5% on time and its weakest Jan–Mar 2026 at 80.7%, a swing of 14 points on roughly 72 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.

The worst days
Worst days for AS 353
The latest arrival of the period was on 13 March 2026, 3 hours 57 minutes behind schedule; most of its delay minutes were filed as extreme weather. On three of the five worst days the largest share was filed as carrier-caused (crew, maintenance, fuelling, baggage).
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 13 March 2026 | 3 hours 57 minutes | Extreme weather |
| 29 March 2026 | 3 hours 23 minutes | Carrier |
| 20 July 2026 | 2 hours 53 minutes | Carrier |

Delay causes
Why AS 353 runs late
Carrier accounts for 52% of the 1,919 delay minutes carriers reported here, and the remaining four split what is left.
- 52%Carrier
- 18%National Airspace System
- 16%Extreme weather
- 14%Late-arriving aircraft
Extreme weather accounts for 16% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.6 times the usual weather exposure. The split is drawn from 1,919 delay minutes reported on AS 353.
Cancellations are rare at 0.55%, 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 2.5% 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 2,561 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 361 flights under AS 353 in the data flew PDX to OGG. 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. 361 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 353
For a booking, AS 353 has one of the better records a US domestic flight can show: 88.0% on time and 0.55% cancelled. That is a base rate, not a promise about any single day.
