It seems every flight I've had with EZY or RYR in the last two years, without exception, has been delayed because of excessive cabin baggage. It's been so bad lately that even MOL has popped up to complain about passengers bringing 'half their house' with them on the flights. Strangely enough, I've not seem the same sorts of delays on BA.
What I find particularly annoying is passengers who bring oversize bags on board, complain when no space is left in the overhead bins, and so get their bags loaded into the holds --- free of charge ---- while those of us who checked our bags are charged. It's a form of fraud in my book.
