Your odds as a retiree

Category VI is the last group called at roll call, and the fear is that nothing is left by then. The record at MCAS Iwakuni says otherwise: 33 percent of the 182 reported flights had room by the time Cat VI was called. This is one of the tougher terminals for retirees, so flexibility and a backup plan matter more here than most places.

Timing matters here. October and March have been the friendliest months, with retirees getting on 100 percent of reported flights at the top of that range. December has been the toughest at 0 percent. If your dates can move, move them.

By raw volume, April and December saw the most departures in the year ending September 2026, and September the fewest. A busy month means more chances, not better odds, and both numbers matter when you pick a window.

One caution worth passing on. These counts cover the roll calls that get published. Terminals miss days and some flights never make the public boards, so the true number is higher than any tracker can see. And the terminal always has the final word: call before you drive.
