I have to concur with the easyJet pilots contributing on here. I believe that easyJet is a good place to work right now, for all its faults, but I would be struggling to see a much better place to work in the UK, with the possible exception of BA. Even that option would depend on how old you are and how long you're willing to wait for promotion.
Regarding the risk in coming here as flexi crew pilots, I would have to agree that the days of quick commands are long gone. Nonetheless if I was a UK charter pilot right now I would be very worried about the future. EasyJet is not the best-paid airline around, but it is certainly one of the most secure. Right now that makes it an extremely attractive place to work. The other factor in the temporary contract argument is that if the background project works out, there is likely to be a substantial improvement in those terms and conditions. Most critical, there is likely to be a move towards permanent employment status much more easily that has been the case in the past. What that means in practice is that coming here on the temporary contract is no longer the risk it once was. The European economic situation is clearly very uncertain, and that could lead to significant difficulties for all our lives. I move away from easyJet would not seem very sensible to me.
