Space-A Scout › Routes › Andersen AFB to Seattle-Tacoma Intl
In the year ending November 2026, 28 Space-A flights went from Andersen AFB to Seattle-Tacoma Intl. That is every week or two, and roughly 14 percent of Andersen AFB's recorded departures. On the 26 of those where the terminal reported who made the cut, Category VI travelers, the retirees and veterans at the back of the line, got a seat 88 percent of the time.
By raw volume, June and October saw the most departures on this route in the year ending November 2026, and December the fewest. The route was active in 13 of the 14 months on record.
Category VI is the last group called at roll call. On this route, 88 percent of the 26 reported flights still had room by the time Cat VI was called. Not a sure thing, but far from hopeless, and picking your month improves it.
The lowest category that made each reported flight, in the year ending November 2026:
| Category II | 2 flights |
| Category IV | 1 flight |
| Category VI | 23 flights |
Seats are the other half of the picture. On the 26 flights that reported both numbers, the terminal released an average of 96 seats and 40 were taken, so a typical flight on this route left with about 56 Space-A seats empty. That is a lot of room, and it is why the Category VI number above is as good as it is.
A schedule on the 72-hour board is a plan, not a promise, and on this route the record says how much of a plan. Of the 18 flights posted to Andersen AFB's board for Seattle-Tacoma Intl in the last 120 days, 3 (17 percent) disappeared from the board more than twelve hours before they were due to fly, 3 (17 percent) changed their roll-call time after first posting, and 1 (6 percent) changed their seat count. Normal turbulence for Space-A. Check the board the night before and again the morning of.
