When I booked another set of tickets, I doubled checked our birthdays when booking. When I went to modify passenger details after booking, the birthday is -1 day once again.
Do I need to call? Is this a website error?
You will be able to update your UA FFP during OLCI or CI. It's a AI quirk.
Your birthday doesn't matter (unless you're inviting me to have some good whisky), it's probably a timezone thing that has caused the problem, I'm guessing. It doesn't matter to FFP validation.
