This morning I checked in for my flight tomorrow, but was told I can't be issued a BP. It also displayed the 'we need to check your passport' message in MMB it shows when you go transcontinental. I'm going to Sweden...
Then about 3 hours later all that went away and it issued the BP no problem, and that message disappeared.
If you didn't use BA much that sort of thing could care the heck out of you; it's only through assuming that it's IT failing that we don't all have mini panics every time.
