Things are getting more complicated:
The Committee on Climate Change has called for Air Miles schemes to be axed. Greg Dickinson says we should go one step further and penalise frequent flyers
I have been guilty of both being a frequent flyer and using airmiles so I am not in a position to criticise however, the potential impact on prices and passengers makes for an interesting discussion.
Behind a paywall but:
Axing Air Miles
