AS100 route overview: ANC to SEA

AS100 distance and great-circle path

AS100 covers 2,326 km, or 1,445 miles. That makes it a medium-haul flight, long enough for a full meal service, short enough for narrowbodies. Of the 367 routes we track, it ranks 254 by distance.

The shortest path from Anchorage to Seattle is a polar one. It leaves on a 118° heading and bends far closer to the top of the globe than the 2,326 km figure suggests on a flat map. Watches move 1 hour forward between the two gates.

Our guide explains how the ANC-SEA route appears on a tracker map.

Can the Boeing 787-9 Dreamliner comfortably fly AS100?

Not at all. At roughly 17% of its range, this is an easy trip for a Boeing 787-9 Dreamliner. The airline picked it for cabin size, not distance. The full numbers are on our aircraft page for the Boeing 787-9 Dreamliner.

What to know about AS100

  • Time change: you land 1 hour ahead of the time you left.
  • Flies far north: the real path runs much closer to the pole than a flat map suggests.

What we know about AS100

What flying ANC to SEA takes

It is a medium-haul sector, long enough for a full meal service, short enough for narrowbodies. Alaska Airlines needs a narrowbody on the longer variants, or a widebody where demand justifies it: at this distance the choice is usually about seat count rather than range. In daylight the sun sits on the right (south-facing) side of the cabin for most of the crossing.

How we verified this

The origin and destination on this page are the ones we verified for callsign ASA100 through adsbdb, not a schedule copied from elsewhere. We have logged it airborne on 29 days between 2026-09-20 and 2026-10-18. Timings are observations, not an official operational status: always confirm with the airline before travelling.

This page was published from our own tracking record rather than a third-party schedule feed, so it grows as we see the flight again. The seven-day log below is the raw version of the same evidence.

AS100 activity in the past 7 days

Our database contains 7 observations of AS100 across 7 UTC dates in this window, most recently 2026-10-18. Those records contain 5 distinct transponder addresses. The most frequently resolved route was ANC-SEA (7 records).

The median recorded visibility was 545 minutes. That is time inside receiver coverage, not airborne duration or an on-time-performance measurement.

How much CO2 does AS100 emit?

Worked from the great-circle distance and the fuel burn measured for Boeing 787-9, the aircraft normally flying this route. Carbon dioxide only - see the method below.

Distance flown2,326 km
AircraftBoeing 787-9 Dreamliner
Fuel burn rate5.78 kg per km
Fuel burned13,433 kg
CO2, whole flight42.4 tonnes
Seats, typical layout290
Passengers carried241 at an 83% load factor
CO2 per passenger176 kg

Where that lands by cabin

The aircraft burns the same fuel whoever is aboard, so the cabins divide one total rather than each carrying their own. A seat's share is the floor it takes up, which is why an economy seat comes out below the 176 kg cabin average and a flat bed well above it.

Economy238 seats, 198 flown
127 kg CO2 per seat
Business44 seats, 37 flown
369 kg CO2 per seat
First9 seats, 7 flown
509 kg CO2 per seat

Taken whole, AS100 emits what 707 trees take back out of the air in a year. One economy seat on it accounts for about the same carbon dioxide as driving a petrol car 1,036 km, or 5,032 km of the same journey by train.

How this is worked out. Fuel burn is read from published measurements of this type, taken at sectors of 6,204 km, 9,208 km and 12,116 km, all longer than this route, so the closest is held flat and the real figure is likely a little higher. It counts carbon dioxide only, and the cabin split assumes the layout typical of this size of aircraft. Read the full method, sources and caveats, or put AS100 against another flight.
