Traveling from US to UK and back, Dual Citizen question
Sorry if this is in the wrong forum, please move if appropriate.
I am a UK citizen that lives in the US and I will (hopefully) also soon be a US citizen.
Shortly after that, I have to take a trip back to the UK. I'll be flying PVD-EWR-MAN-EWR-PVD.
I'm a little confused about which passport I would use at each point of my journey. Obviously by law I just enter and exit the US using my US passport and obviously I want to enter the UK using my UK passport, so I'm not sure which passport to use/show at each point, starting with booking the ticket at united.com.
I have read a few guides to traveling as a dual citizen online, but they all seem to offer slightly differing advice.
Are the any US/UK dual citizens on flyertalk who travel between the two countries regularly that could walk me thought their process?
Thanks.
