Hi Guys
This is an interesting topic and the inconsistency amongst airlines is undoubtedly the reason many pax get irritated at having to show us their boarding cards. It still amazes me that even our most regular passengers assume we are checking their seat number and not the flight number and date. Just last week I spotted three wrong boarding cards on one flight - it was just that pax had handed over the incorrect one ie. their outbound card or one from a previous date to same destination. I have heard that the CAA come on and check we are adhering to this procedure. After a while it just becomes second nature.
Thats my 10p's worth!!
Take Care Everyone x
