This is a new one for me. When trying to check in online, I get "Passport information required - why" "Add passport information". When clicking on "Add passport information", I get "Information completed", and "Go to online check-in". Then, when clicking on "Go to online check-in, I am taken back to "Passport information required". And so forth.

Arrrrrrgh... So I phoned BA. Got connected to Indian call centre - a first for me. Had to read PNR three times (agent didn't seem to understand that a PNR contains digits at least as letters). Then my name. Then asked to *spell* my e-mail address. Then a long spiel about sir, would it be acceptable to you if I address you by your first name. Then she just proceeds to tell me, in long-winded terms, exactly the same problem that I have just described to her. Five times. Interspersed by two periods on hold. After which, sir, there is nothing to worry about sir, you just need to go the check-in counter at the airport tomorrow.

Well thanks, pal, let me be the one who decides whether or not to worry. I have a same-day return to Paris tomorrow, and have zero interest in interacting with airport check-in counters. Maybe I've been lucky, but I've never had any problem checking in online with BA before. Neither have I had to deal with their Indian call centre. The combination of creating a needless problem and switching to an outsourced call centre that doesn't understand the problem and is not empowered to solve it is a new low in my experience with BA. And your system can't check me in and I have to go to the check-in counter, then I'd rather be told so by ba.com than having to waste 15 minutes of my time and money on an utterly frustrating and pointless phone conversation with the exact same outcome.
