Where celebrities are concerned, "loyalty / ambassadorship" is almost exclusively a quid pro quo situation. Celebrities live and breathe free anything - tickets or discounts or preferential treatment, free publicity, lounge memberships, invites to miscellaneous open nights / AO tennis, grand finals, sponsorships, yada, yada, yada. It is ingrained in their psyche by their managers (and fellow celebrities, no doubt) to expect some form of payola for anything they do. Even being photographed in a particular designer's clothes warrants a free top-up of one's wardrobe. It's a bit rich for these 2 girl-children to characterise their relationship with QF as one of, ostensibly, one of benevolence on their part towards the airline.
