Which passport should my dual citizen kid register for flights from Japan to the US, and then from the US back to Japan?
I’ve searched for previous posts and it is very clear about which passports to present to border control (US passport to US border control, Japan passport to Japan border control), but I’ve found a lot of conflicting information about which passports to register with the airline after booking the tickets. Can anyone share what they know? Her name is the same in both passports, and the flights are booked separately if it makes a difference.
Thanks!
