I can agree with you on Air Berlin although Nuremburg seems to just aboout be holding its own but Air Asia X would have left regardless of the airport as it was due to their longer routes nothing cheaper enough compared to the competition. Add in the Government diving into the pockets of every passenger they carry with apd and the EU who have their 'carbon trading tax' or whatever it is called and it's not hard to see why they pulled out of LON and their other longer markets. It was down to them not having a large enough price difference to warranty a poorer on board product vs Malaysia Airlines and the Middle East big 3, not because they changed airports!
