After its first crewed test flight in April 2024, Boeing's Starliner is expected to fly with a crew once a year.

This is judged as a forecast that Starliner would fly a crewed mission about once a year after its first crewed test flight, tested over the first full year after that flight (calendar 2025). True: the crewed test flight took place in 2024 and at least one more crewed Starliner flight launched in calendar 2025. Mostly true: the same holds, but the test flight took place in a month of 2024 other than April. Mostly false: the next crewed Starliner flight launched after 2025 but by the end of 2026. False: no crewed Starliner flight launched in 2025, as shown by NASA's flight schedule or reports that missions were delayed or turned into uncrewed or cargo flights, and none launched by the end of 2026 either.

Set before the research began.

   “Starliner launched June 5, 2024, on its first crewed test flight to the International Space Station.”

2. E2 NASA, Boeing Modify Commercial Crew Contract - NASA NASA · 24 November 2025

   “NASA and Boeing are targeting no earlier than April 2026 to fly the uncrewed Starliner-1 pending completion of rigorous test, certification, and mission readiness activities.”

3. E3 Next Crewed Boeing Starliner Flight Not Until 2028 SpacePolicyOnline · 28 September 2026

   “Isaacman said Starliner-1 will launch no earlier than December of this year and Starliner-2 not until 2028.”

4. E4 NASA cuts missions for Boeing Starliner contract, next flight will have no crew Orlando Sentinel · 24 November 2025

   “The next trip to space for Boeing’s beleaguered Starliner spacecraft won’t have a crew on board after NASA announced changes to the commercial crew contract that also slashes the total number of missions to the International Space Station.”

NASA confirms the first crewed Starliner test flight launched on June 5, 2024 (E1). In November 2025, NASA and press reports said the next Starliner flight, Starliner-1, would carry no crew and was targeted no earlier than April 2026 (E2, E4), so no crewed Starliner flight launched in 2025. In September 2026, Isaacman said Starliner-1 would launch no earlier than December 2026 and Starliner-2 not until 2028 (E3); with the next flight planned as uncrewed (E2, E4), this leaves no crewed flight expected by the end of 2026.
