To be fair, AMM, DME are probably routes that Easyjet will, quite naturally, look at from time to time and eventually they will be launched IMO. However, I think we're perhaps 6 months to a year before they would be launched and I still believe LGW will be the proving ground as it quite often the case.
If I am to believe what I have been told by someone responsible for route planning, U2 will be sticking with trusty old PMI for it's one and only new route for next Summer out of MAN. The problem with Easyjet is that bases are competing for aircraft as deliveries slow down and I think for the next year or two MAN will see some of the more "mundane" destinations such as PMI, LIS etc which are all equally as important to airline and airport alike.
