I think maybe BA and Oneworld sort out the rules who is allowed in and who isnt. Also maybe a self check in computer system as hotels have installed to save time for people who dont need to get nagged.

If my Doctors can do it, I am sure BA can. Although I did get told off last Monday by the line fo people waiting for staff. Just incase anyone needs to know the old lady is No1. But as I wasnt even joing to line, there was no need for her insults.
