We are hoping to fly to the US on Thursday. My teenage son's passport expired in May and we were only able to get a renewal appointment two weeks ago - we are concerned that the new passport may not arrive in time for us to travel. I've contacted the Embassy but my understanding is that I can only do that by email and I've not yet had a response.
If we are not able to get his US passport (either the new one, or an emergency one, or have the expired one returned to us), would it be possible for him to fly on his UK passport, since he is our child and would be travelling with us? I saw on another thread a question about a non-US citizen spouse travelling on a UK passport, and the person was advised to have their ESTA up to date - is that something we would need to do (and what does that involve - have never had to worry about this before! It was recommended in the other thread that they do something at the airport rather than online, which I didn't really understand)? Would we need to take his birth certificate when we go to the airport?
Hoping to get the US passport in time but just trying to figure out what might be possible if not. Thanks for any advice anyone can give!
