easy has been through a bad patch (rostering, etc.) from which it is now emerging. Life's not perfect, but where is? It's one of the most secure jobs in the industryat present so ain't a bad place to be, all things considered.
The grass isn't always greener on the other side! Ryanair fly the nuts off their pilots. So do easy, but I suspect to a marginally lesser extent (ignoring the rostering disasters of the past few months), and with the Go integration I suspect the final aircraft (and crew?) patterns in the 'new easyJet' will come somewhere between the eJ high utilisation patterns and the Go crew friendly / operationally robust flying lines.
Personal choice as to jumping ship. Personally I plan to hang on a couple of months and see how things pan out.....don't want to make a rash decision and regret it in months to come.
