I have a rather specialist question about a passport issue and what BA's likely behavior will be. I am my family are UK ex-pats living in the USA as Permanent Residents, with shiny Green Cards. We have Global Entry, and when we re-enter the US, the machines are only interested in our Green Cards. Tomorrow we leave for a week in England with family/friends, and my younger child, who is ten, has a UK passport which expires in April. I had intended to renew it during our week in England, but find now that you cannot get a child's passport on a same day appointment, which really means we will have to do it by mail from the US when we are home.

But... do you think BA check in staff will issue him a boarding pass, given he is under the 6-month passport validity to travel rule? The US authorities will not give a damn about this, because our GCs are valid for another seven years - but will a British BA staffer understand that our GC trumps our passport as permanent residents in the USA? If I have zero chance of him being allowed to fly back in early January, that demands a different course of action to if he is going to get on the plane with me and the rest of his family just fine!

This is specialist, I know, but the amount of expertise lingering on this thread is so enormous, I'd welcome any opinions, especially from other GC holders.
