NASA Plans Boeing Starliner Crewed Flight in 2028

The schedule effectively resets Starliner's operational timeline, with an uncrewed demonstration preceding a crewed flight by roughly a year or more. That gap matters for the ISS's crew rotation planning, since it leaves SpaceX's Dragon as the sole certified U.S. crew vehicle for longer than previously expected. The open question is whether the uncrewed test stays on its narrow December–January window, given how often this program has slipped.
