Hello.

I have read a lot of conflicting information about using two passports (a UK and an EU one) when flying after Brexit on BA.

I am reconciled at some stage to getting things wrong. I also appreciate I won’t be the only one using two passports for the first time shortly, and fully acknowledge how lucky I am to have the option. But does this sound right to people who have had to do this kind of thing before?

1) I book my flight from the UK to the EU.
2) Because I am flying to the EU, I change the info in my BA account from my UK passport to my EU passport.
3) I check in and present BA staff at the gate with my EU passport.
4) I land in the EU, showing my EU passport and go about my business.
5) Before I travel back to the UK, I change the info in my BA account from my EU passport to my UK one.
6) Show border agents from the EU country my EU passport.
7) Show BA staff at the gate my UK passport.
8) Land in the UK and show my UK passport at the border.

Is this the right order? Does it matter when I change the info in my BA account for the purposes of ensuring the right border force have the right API?

Thanks for any help!
