Well BA has all my details including all my passport info and has had this info for about 20 years with my latest passport data added when it was issued 2 years ago. So why all of a sudden does online checkin now want all my passport data again? This happened last week when I checked in for my flight to DXB and now it wants it again for the return. Never had this before since I started using online check in when it was introduced way back when.

It will not let me past this stage without entering all this stuff again.
