I was in Nice. Easyjet running with about 30 minutes delay. BMI (my flight) departed 1.25 hours late, finally deplaned 3.5 hours late (an an hour on the ground at LHR waiting for a gate), but they got us home. BA cancelled (quote from board behind BA desk at Nice) "because of 100 kmh winds!!!!" (they were down to 25 kmh by that time). And your on your own because it's not our fault.
Great publicity for BA: people so glad they paid more to travel with a full service carrier.
