I can't believe that I'm the only person who currently routinely transits the UK with arrivals and departures on separate tickets that will begin thinking twice and three times about the economic sanity of such behavior.
For passengers transferring between flights booked separately, I frankly find it very, very odd that APD at current elevated levels (GBP 90- 110 for long-haul flights) hasn't become like all other taxes i.e. something to be avoided at all costs.
Common sense dictates that either a practical workaround will be found (and spread via bulletin boards like this one). or that such transfer passenger traffic will soon fall sharply off.
Does anyone know whether one of the goals of the APD was to reduce the attractiveness of the UK as a transit point between airlines?
