Space-A Scout › Routes › Yokota AB to MCAS Iwakuni
In the year ending October 2026, 59 Space-A flights went from Yokota AB to MCAS Iwakuni. That is about once a week, and roughly 9 percent of Yokota AB's recorded departures. On the 34 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 74 percent of the time.
By raw volume, December and September saw the most departures on this route in the year ending October 2026, and August the fewest. The route was active in 13 of the 14 months on record.
Friday is the day to watch: 40 of the 59 roll calls for this route, 68 percent, fell on a Friday.
Category VI is the last group called at roll call. On this route, 74 percent of the 34 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 III | 5 flights |
| Category IV | 1 flight |
| Category V | 3 flights |
| Category VI | 25 flights |
Seats are the other half of the picture. On the 53 flights that reported both numbers, the terminal released an average of 15 seats and 2 were taken, so a typical flight on this route left with about 13 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 10 flights posted to Yokota AB's board for MCAS Iwakuni in the last 120 days, 0 (0 percent) disappeared from the board more than twelve hours before they were due to fly, 4 (40 percent) changed their roll-call time after first posting, and 2 (20 percent) changed their seat count. Unusually steady for Space-A, which makes this a good route to plan around.
