These figures cover 272 flights between September 2025 and August 2026. The median arrival is 17 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.

The worst days
Worst days for AS 98
The latest arrival of the period was on 24 October 2025, 2 hours 12 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). On three of the five worst days the largest share was filed as extreme weather.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 24 October 2025 | 2 hours 12 minutes | Carrier |
| 9 October 2025 | 2 hours 10 minutes | Carrier |
| 21 December 2025 | 1 hour 29 minutes | Extreme weather |

Delay causes
Why AS 98 runs late
Carrier accounts for 52% of the 1,374 delay minutes carriers reported here, and the remaining four split what is left.
- 52%Carrier
- 19%Extreme weather
- 18%National Airspace System
- 12%Late-arriving aircraft
Extreme weather accounts for 19% 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 3.1 times the usual weather exposure. The split is drawn from 1,374 delay minutes reported on AS 98.
Cancellations are rare at 0.37%, 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 1,448 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.
The same number turns up on one other city pair in the data, including SFO to LAS (29), but none flew often enough under AS 98 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ANC to SEA only.
One caution: this is a thin sample. 272 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 98
For a booking, AS 98 has one of the better records a US domestic flight can show: 88.2% on time and 0.37% cancelled. That is a base rate, not a promise about any single day.
