easyJet
In fact there were four easyJet cancellations from BRS yesterday because I had forgotten the morning Edinburgh was also cancelled.
easyJet was not the only airline affected by lengthy delays into Bristol last evening - Ryanair had two with one (Malaga from memory) not expected until 0330 (four hours late) but they didn't cancel any flights.
Delays are part and parcel of air travel as is the occasional cancellation but it's the scale of recent cancellations by easyJet that is disturbing.
