^ This. When we got back into the gate (having been sat in the returned plane for over an hour) I checked the available flights - IIRC three seats remained on a flight to Liverpool, and nothing else that would get us closer (our original flight being Manchester). I booked them immediately.

The alternative would have been waiting to see an easyJet representative, in an overcrowded gate, two days before Xmas. Those seats would have gone. I've been through Geneva airport enough times to know how it functions and that we were going to get bumped to the next day.
