2planks, looks like EZY are leaving after December by most accounts. The flights look to have done quite well, but the Amsterdam has had load factors of as low as 50% during the summer and around 60% at the most. People in Easyjet say yields are not too great, and that the aircraft would be better used in either expansion at MAN/LGW or on the continent.
Could be that they agreed to do the flights in order to show VAS that it was growing so they could sell their 65% shares in the airports.
