Can One Board a Flight to the US with an Expired US Passport?
i don't think I've ever seen this question answered - usually, it comes up, and morphs into a discussion of how to get an ESTA in the non-American passport to get aboard the flight. I'm not asking about ways to get back to the US if stuck abroad, and yes, we all know, as a US citizen once you make it to the US you will be admitted.
Also not asking about how this might be finessed at airports with US pre-clearance (e.g., Canada, Ireland.)
Again, the question - anyone know whether airlines will allow someone to board a US bound flight if the only passport held by the passenger at flight time is an expired US Passport?
