What we know about AS585

What flying LAX 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.

How we verified this

The origin and destination on this page are the ones we verified for callsign ASA585 through adsbdb, not a schedule copied from elsewhere. We have logged it airborne on 41 days between 2026-09-19 and 2026-10-29. 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.

AS585 activity in the past 7 days

Our database contains 8 observations of AS585 across 8 UTC dates in this window, most recently 2026-10-29. Those records contain 7 distinct transponder addresses. The most frequently resolved route was LAX-SEA (8 records).

The median recorded visibility was 1437 minutes. That is time inside receiver coverage, not airborne duration or an on-time-performance measurement.

How much CO2 does AS585 emit?

Worked from the great-circle distance and the fuel burn measured for Boeing 737-900ER, the aircraft normally flying this route. Carbon dioxide only - see the method below.

Distance flown1,537 km
AircraftBoeing 737-900ER
Fuel burn rate3.83 kg per km
Fuel burned5,885 kg
CO2, whole flight18.6 tonnes
Seats, typical layout178
Passengers carried148 at an 83% load factor
CO2 per passenger126 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 126 kg cabin average and a flat bed well above it.

Economy157 seats, 130 flown
104 kg CO2 per seat
Business21 seats, 17 flown
301 kg CO2 per seat

Taken whole, AS585 emits what 310 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 739 km, or 3,590 km of the same journey by train.

How this is worked out. Fuel burn is read from published measurements of this type, taken at a 926 km sector, the only published sector for this type, applied to this route's 1,537 km unadjusted. 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 AS585 against another flight.
