Don't worry, after the first season easy will drop the longer routes it has acquired with GB and redeploy the aircraft where they will better fit the LoCo business model. I don't think the 321 will be retained either - 210 passengers and their bags off and another 210 and their bags on in a 30 minute turn around? I don't think so. We often struggle to do it with 156 on the 319.
Monarch? Not likely at the moment, I think, with 2008 looking uncertain and hands full integrating GB. I rather think the high-priced help at Hangar 89 will just wait to see which competitors go to the wall in 08/09 and expand into the vacuum when the time is right. But what do I know? I'm only a pilot and the CEO has already reneged on one of his pronouncements when he decided to buy GB.
