Why the old passport still works
A deed poll or a marriage certificate changes your name, not your passport. HM Passport Office cancels an old passport when it issues the replacement, so until you send it off with an application, the passport in your old name is still valid. That is why the name on the booking matters more than the name on your bank card: the airline and the border check the booking against the passport, and nothing else.
Visas, ESTA and ETIAS
- Visas belong to the passport they are in. GOV.UK warns that unexpired visas in your old passport may become invalid if you change your name, so ask the country that issued them.
- A US ESTA has to be applied for again after a change of name or a new passport, the official ESTA site says.
- ETIAS, the EU's travel authorisation, has not started; the EU expects it in the last quarter of 2026. Each one will be linked to one passport.

Questions people ask
Can I travel with a passport in my maiden name?
Yes, if the booking is in your maiden name too. Marriage and a change of name do not cancel a passport, and GOV.UK's rule is that the name on your passport must match the name you book in.
Which name should I book my flight in?
The name on the passport you will travel with. While your passport is in your old name, book in your old name; once the new passport arrives, book in your new name. GOV.UK advises not booking travel until you have a valid passport.
Do I need a new ESTA after changing my name?
Yes. The official ESTA site says you need a new travel authorisation if you change your name or get a new passport. While your passport is still in your old name, you apply in that name and give your new name as another name you are known by.
Can I get a passport in my married name before the wedding?
Yes, up to three months before the ceremony. HM Passport Office post-dates it, so it cannot be used until the day, and your current passport is cancelled when you apply. Changing your name before the wedding
