Hi all

I am having a bit of a nightmare. My mum is meant to be travelling to the US on BA on Tuesday- when getting her covid pass, we realised that her NHS record is in her married name and her passport is in her maiden name. We are going to the GP surgery first thing tomorrow morning to try and get her name changed but i am worried that we cant get this done in time.
Would she be able to take her marriage certificate with her to the airport? Its falling apart as its over 50 years old but i am trying to think of back up plans!
