Only the person named on the ticket may use it, but don’t worry if you’ve just made a tiny spelling mistake. There’s no need to let us know, just turn up and travel as normal.
 
If your passport's in your maiden name but your ticket's in your married name, just bring a copy of your marriage certificate with you when you travel. There’s no need to make any changes to your booking or let us know in advance.
 
If someone else would like to travel, they'll need to book a new ticket.
