Space-A Scout › Routes › Yokota AB to Diego Garcia
In the year ending September 2026, 112 Space-A flights went from Yokota AB to Diego Garcia. That is about twice a week, and roughly 17 percent of Yokota AB's recorded departures. On the 41 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 78 percent of the time.
By raw volume, May and March saw the most departures on this route in the year ending September 2026, and October the fewest. The route was active in 13 of the 13 months on record.
Sunday is the day to watch: 40 of the 112 roll calls for this route, 36 percent, fell on a Sunday.
Category VI is the last group called at roll call. On this route, 78 percent of the 41 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 September 2026:
| Category II | 2 flights |
| Category III | 7 flights |
| Category VI | 32 flights |
Seats are the other half of the picture. On the 104 flights that reported both numbers, the terminal released an average of 9 seats and 0 were taken, so a typical flight on this route left with about 9 Space-A seats empty. Some room most days, but not so much that showing up late is safe.
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 25 flights posted to Yokota AB's board for Diego Garcia in the last 120 days, 2 (8 percent) disappeared from the board more than twelve hours before they were due to fly, 1 (4 percent) changed their roll-call time after first posting, and 3 (12 percent) changed their seat count. Unusually steady for Space-A, which makes this a good route to plan around.
Sign-up at Yokota AB is free and does not commit you to anything. You can email the terminal at 730ams.org@us.af.mil (the email doubles as your dated proof of sign-up), use the AMC online sign-up portal and call 011-81-3117-55-7111 / 011-81-3117-55-5661 / 011-81-3117-55-5662 to confirm anything time-sensitive. 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.
