Space-A Scout › Routes › Seattle-Tacoma International Airport to Yokota AB
The Seattle-Tacoma International Airport to Yokota AB run came up 80 times in the year ending October 2026, about twice a week. On the 68 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 51 percent of the time.
By raw volume, September and July 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.
Thursday is the day to watch: 45 of the 80 roll calls for this route, 56 percent, fell on a Thursday.
Category VI is the last group called at roll call. On this route, 51 percent of the 68 reported flights still had room by the time Cat VI was called. This is one of the tougher routes for retirees, so flexibility and a backup plan matter more here than most places.
The lowest category that made each reported flight, in the year ending October 2026:
| Category II | 7 flights |
| Category III | 20 flights |
| Category IV | 3 flights |
| Category V | 3 flights |
| Category VI | 35 flights |
Seats are the other half of the picture. On the 79 flights that reported both numbers, the terminal released an average of 9 seats and 7 were taken, so a typical flight on this route left with about 2 Space-A seats empty. That is tight. This route fills, and being early in the sign-up order matters more here than the category rate alone suggests.
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 13 flights posted to Seattle-Tacoma International Airport's board for Yokota AB in the last 120 days, 0 (0 percent) disappeared from the board more than twelve hours before they were due to fly, 1 (8 percent) changed their roll-call time after first posting, and 1 (8 percent) changed their seat count. Unusually steady for Space-A, which makes this a good route to plan around.
