Agree with F3G. Personally for me one of the biggest frustrations of flying regularly is the lack of standardisation - even with the same airline (and it's not just the Boarding card issue either). At times it comes down to the individual and their mood of the day. So one day I board with BC in hand and get a disinterested F/A. The next day I board (same airline) not having my BC in hand and get the God-help-me look from the F/A who, this time, wants to check it. You just can't win, and the passenger is always wrong!
