BALPA has shown the 80% of the population will take a long haul flight from AMS rather than from the UK due to APD and taxes but still GB refuses to see it
Which conversely infers that short haul carriers a la easyjet should see their passengers numbers increase whereas BA, Virgin and others should see their numbers fall from the UK.
Not sure how easy it is to interline via Schiphol if you arrive on ezy but would rather think it will be AF/KLM who will benefit from this. Concerted action by all parties with a vested interested saw dropping of APD at AMS.
