The Times reports the following:
"The heads of several big companies that called for a third runway at Heathrow are members of a confidential British Airways club of elite businessmen who receive special favours.
They are served by a team of BA staff who cater for their every need. Other passengers are sometimes bumped off flights to make way for them, according to a BA source. Staff meet members at the aircraft door to fast-track them through immigration and flights are sometimes held to ensure they make their connections.
The only way to become a member is by personal invitation from either Willie Walsh, chief executive of BA, or Martin Broughton, the chairman. No one can earn the right to join by frequent flying.
Members get a black Premier card and distinctive black luggage tags, which BA staff are trained to look out for."
I am sure that being given the Premier card didn't influence them in the slightest.
