I thought it was very strange charging for handluggage as I'm not aware that any other airline charge for that, not even Ryanair, so.. The thing is that I've heard it from a girl working at the sales desk from Jet2, that they will begin charging it by the end of the month or so.. UNLESS she missunderstood it and they'll only charge oversized ones like you said, that would make more sense.. I'll try to find out the truth.
