I haven't flown UA in a while, though this has never been a problem.

I'm from the UK, so we express our dates of birth day/month/year. My d.o.b is inputted accordingly within my MP account.

I went to book a flight today, and for some reason the website now sees my d.o.b. in US terms i.e. month/day/year. 'No problem' I think, so I go to change it to the US-style. 'Oh no,' says UA.com, 'you have to email proof your date of birth has changed.' Sigh.

Any suggestions welcome.
