Every gateway with a record

Ranked by how often the route ran. Seats are the average released and taken per flight where the terminal reported both. Each row links to the full route page.

Gateways that flew to Osan AB fewer than twelve times, or whose last flight there was more than ninety days ago, are left off rather than padded. They still show on the live boards when they post.

How to choose

From	Roll calls	How often	Cat VI made it	Seats out / taken
Seattle-Tacoma International Airport	56	about once a week	74%	16 / 8

Frequency is chances; the category rate is odds per chance; empty seats tell you whether a low rate means a full airplane or an empty roll call. A gateway that runs the route most days at 80 percent usually beats one that runs it monthly at 95. Then pick the month: the timing guide has the year-wide pattern and each route page has its own. Then sign up at every gateway you might use, because sign-ups are free and the date is your place in line.

By the record, Kadena AB: Category VI made the cut on 96 percent of its 33 reported flights to Osan AB in the year ending September 2026. Read that with the seat numbers on the route page, since a roomy route with a slightly lower rate can be the better bet.

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.
