Specifically a BA Premier card, apparently.

Perks of the Premier Card, according to The Times, are:

— Members can get seats on full flights, meaning that someone else is bumped off

— Flights are held if a member’s connection is late

— Cardholders are met by BA staff at the door of the aircraft to be fast-tracked through immigration

— They get upgrades from business class to first and from economy to business

— They receive a contact number for “special services”, who will trace lost bags and fulfil special requests
