Space-A Scout › Routes › Yokota AB to Seattle-Tacoma Intl
The Yokota AB to Seattle-Tacoma Intl run came up 84 times in the year ending October 2026, about twice a week. On the 80 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 79 percent of the time.
By raw volume, August and September saw the most departures on this route in the year ending October 2026, and November the fewest. The route was active in 13 of the 13 months on record.
Saturday is the day to watch: 41 of the 84 roll calls for this route, 49 percent, fell on a Saturday.
Category VI is the last group called at roll call. On this route, 79 percent of the 80 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 October 2026:
| Category II | 3 flights |
| Category III | 10 flights |
| Category IV | 1 flight |
| Category V | 3 flights |
| Category VI | 63 flights |
Seats are the other half of the picture. On the 83 flights that reported both numbers, the terminal released an average of 41 seats and 17 were taken, so a typical flight on this route left with about 24 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 28 flights posted to Yokota AB's board for Seattle-Tacoma Intl in the last 120 days, 4 (14 percent) disappeared from the board more than twelve hours before they were due to fly, 2 (7 percent) changed their roll-call time after first posting, and 9 (32 percent) changed their seat count. Normal turbulence for Space-A. Check the board the night before and again the morning of.
Sign-up at Yokota AB is free and does not commit you to anything.

Do it 45 to 60 days before you want to travel, because your place in line at roll call is your sign-up date, and a sign-up is good for 60 days.
