Matter of fact, easyJet Switzerland get very good service at GVA from ATC.
It is looked at by many Genevois as their local airline, since Swissair pulled a lot of their long range flights out of GVA some years back (this may change..) and Swiss World never got off the ground.
Problem is that the place is b... expensive -not just for easy but for all operators. Just recently, however, EZS has negotiated a deal which will benefit all operators with many movements in GVA - including Swissair, by the way.
So no - the one sided comments above do not apply.
