AS93
Seattle (SEA) to Anchorage (ANC) · scheduled 11:00 AM – 1:38 PM
How AS93 performs
605 operations, July 2023 – June 2026.
AS93 arrived on time 62.9% of the time, against 75.8% for all SEA → ANC flights, so this departure is 12.9 percentage points worse than the route as a whole. Against Alaska Airlines’ own flights on this route it is 11.2 points worse.
AS93’s scheduled departure has moved during the period FlyerIntel has on file: it typically left around 11:00 AM earlier on, and around 11:30 AM more recently — a 30-minute shift, not the few minutes of day-to-day rounding every published schedule carries. Confirm the current departure time before booking around an older listing.

What stands out
How AS93 compares to other flight numbers, not just to itself.
This flight runs unusually far behind the carrier's own average on this route, worse than 91% of 11,589 comparable flight numbers.
62.9% on time for this specific departure, against 74.1% for the same carrier's other flights on this route.

Why AS93 runs late
Where US DOT attributed the delay minutes on this flight.
crew, maintenance, boarding and fueling, all within the carrier’s control
the inbound aircraft was late, so this flight started late
airspace and airport capacity, including weather-driven flow control
weather severe enough to stop this flight specifically

Does a late aircraft delay this flight?
How often the plane that flies AS93 comes in late, and what that does to the departure.
The aircraft flying AS93 came in 15 or more minutes late on 18% of the departures where its previous flight is known. There are not enough departures in both groups to say how the flight left after a late one and after an on-time one.
Each departure is matched to the flight the same aircraft flew into SEA just before it, using the tail number in the DOT file, 548 of 600 departures in all. A departure is left out when that flight is unknown, was cancelled or diverted, or the aircraft had sat for more than 12 hours. A flight the airline cancelled never left and is not in the count, and one flown by a substitute aircraft is matched to the aircraft that flew it, not to the one first planned.
Against the network at the same turn length
| Share of departures | Inbound landed 15+ late |
|---|---|
| AS93 | 18% |
| Network, same turn | 17% |
The schedule leaves a normal turn: enough time to clean and board if the aircraft is on time, little to spare if it is not.
The network row is every flight with a scheduled turn of 60 to 89 minutes. How often AS93’s aircraft landed 15 or more minutes late is about the same as the network’s. There are not enough departures in both groups to compare how it left.

From pushback to gate
When it leaves SEA late, does that still matter by the time it reaches ANC?
AS93 pushes back an average of 17.1 minutes late and reaches the gate at ANC an average of 11.7 minutes late. The 5.4 minutes between those two figures are slack the published schedule already carries, which is why a late pushback on this flight does not reliably become a late arrival. It spends 21.4 minutes on the taxiways at SEA, 2.4 minutes shorter than a typical SEA departure in the same hour.
On arrival at ANC, AS93 spends 5.5 min taxiing from touchdown to the gate — ground time a connecting passenger sits through before they can even leave the aircraft, on top of however late the flight itself ran. That is about what any arrival at ANC spends on the ground before reaching the gate.
Departure delay is averaged over every pushback and arrival delay over every completed arrival, so the two counts differ by the flights that never reached ANC. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 44,293 departures from SEA scheduled in the clock hour AS93 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at ANC (58,786 flights), not just AS93’s own. More on taxi time.

The hour it leaves SEA
Part of any flight’s record belongs to the clock rather than to the flight. AS93 has one departure time, so this is what that time is worth.
On-time arrival rate. 44,293 departures from SEA are scheduled in the 11 AM–12 PM hour over the period, against 510,205 across the whole day.
AS93 is scheduled out of SEA at 11:00 AM, in the 11 AM–12 PM bank. Departures from SEA in that hour arrive on time 74.7% of the time against 79.1% across the airport’s whole day — the slot alone is worth 4.4 points worse before anything about this particular flight is considered.
The two airport figures cover every departure from SEA to every destination, so they describe the slot rather than this journey — the like-for-like comparison against the route is above. Hours are scheduled local, and a number whose schedule moved between banks inside the period has no single hour and is not described here at all. Why the hour matters.

Other routes AS93 has flown
A flight number is a slot in a schedule, and carriers reassign it. These are the other city pairs this number served in the analysis period.
| Route | Operated | Flights | On time |
|---|---|---|---|
| HNL→SAN Honolulu to San Diego | March 18, 2026 – April 21, 2026 | 35 | — |
| ANC→FAI Anchorage to Fairbanks | December 2–17, 2025 | 16 | — |
| FAI→ANC Fairbanks to Anchorage | October 26, 2025 – November 20, 2025 | 26 | — |
| SEA→JNU Seattle to Juneau | January 5, 2025 | 1 | — |
Because the same number has served different journeys, the statistics above describe only the route AS93 currently operates. Blending them would produce an average of two different flights.

Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. AS93 is placed in the same ordering rather than left out of it; the rows around it are the most punctual departures on the route, not all of them, so this is a comparison and not a rank. Schedules change; confirm the departure still operates before booking around this.
Data and methodology
Calculated by FlyerIntel from 605 records of AS93 operating SEA → ANC, published by the US DOT Bureau of Transportation Statistics. A flight counts as delayed when it arrives 15 or more minutes after schedule. Cancelled and diverted flights are excluded from the on-time rate and reported separately. Flight numbers are resolved as carrier plus number plus route, because the same number serves different routes over time.
