I've just checked the Bristol Airport website departures board and they are showing two EZY flights cancelled today - EZY 6147 to CPH at 1335 and EZY 570 to NCL at 1745.
The strange thing is that all the six based BRS EZY a/c are shown as having left on their first rotations of the day this morning, albeit the flight to AMS was a couple of hours late leaving.
The cancelled CPH flight would be operated by a BRS-based aircraft so, unless it has been cancelled for other reasons, it seems odd that the scheduled a/c has already flown today. The NCL flight is operated by a NCL-based a/c.
Doubtless the local press will have a field day (Bristol may not have good football teams but Bristolians are European champions when it comes to whinging about anything), so it's a good thing for the airline and airport that Monday is a bank holiday.
