The Joint Base Pearl Harbor-Hickam to Osan AB run came up 22 times in the year ending November 2026, every week or two. On the 21 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 86 percent of the time.
By raw volume, September and October saw the most departures on this route in the year ending November 2026, and August the fewest. The route was active in 11 of the 14 months on record.
Category VI is the last group called at roll call. On this route, 86 percent of the 21 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 November 2026:
| Category III | 1 flight |
| Category IV | 2 flights |
| Category VI | 18 flights |
Seats are the other half of the picture. On the 21 flights that reported both numbers, the terminal released an average of 45 seats and 10 were taken, so a typical flight on this route left with about 35 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 33 flights posted to Joint Base Pearl Harbor-Hickam's board for Osan AB in the last 120 days, 7 (21 percent) disappeared from the board more than twelve hours before they were due to fly, 11 (33 percent) changed their roll-call time after first posting, and 14 (42 percent) changed their seat count. Normal turbulence for Space-A. Check the board the night before and again the morning of.
