They are not applying the change retrospectively. Any existing bookings are fine, it is only when there is a ticket being issued or reissued that the new calculations apply. A retrospective change would be , I would suggest, when the UK APD changed and AA (unlike airlines like BA which absorbed the cost themselves) was collecting the additional taxes at the airport for tickets that had been issued in advance of the increase
