I am flying to JFK tomorrow on BA and my friend has just done the online check-in.

She told me that the online check-in would not accept my DOB and would only accept the day before my birthday. She showed me a screenshot of my details she entered when the booking was made, which shows my correct DOB

The check-in process is complete and I have a boarding pass but I’m concerned she had to enter incorrect details. Will there be issues at the airport? I’m more concerned about coming home and check in won’t be accepted.

Anyone else had this issue?
