Space-A Scout › Routes › Travis AFB to Osan AB
In the year ending November 2026, 27 Space-A flights went from Travis AFB to Osan AB. That is every week or two, and roughly 4 percent of Travis AFB's recorded departures. On the 27 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 96 percent of the time.
By raw volume, July and December saw the most departures on this route in the year ending November 2026, and September the fewest. The route was active in 10 of the 14 months on record.
Category VI is the last group called at roll call. On this route, 96 percent of the 27 reported flights still had room by the time Cat VI was called. Those are good odds by any standard.
The lowest category that made each reported flight, in the year ending November 2026:
| Category III | 1 flight |
| Category VI | 26 flights |
Seats are the other half of the picture. On the 27 flights that reported both numbers, the terminal released an average of 54 seats and 23 were taken, so a typical flight on this route left with about 31 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 19 flights posted to Travis AFB's board for Osan AB in the last 120 days, 3 (16 percent) disappeared from the board more than twelve hours before they were due to fly, 6 (32 percent) changed their roll-call time after first posting, and 3 (16 percent) changed their seat count. Normal turbulence for Space-A. Check the board the night before and again the morning of.
