It does seem a bit unfair to offload passengers though who could potentially have made the flight. Reality is, EZY, or no other airline for that matter delays a flight for stragglers. What difference does it make for those who were on-time? They are already on the plane ready to go. It will piss off more people than it will ever please.
What's definitely unfair about EZY's policy is that they only allow their Plus Cardholders and those who have paid for extra legroom seats to take a second carry-on bag... and they are permitted to board the aircraft first.
So everyone else faces the risk of their one and only cabin bag going in the hold.
A ruthless policy blatantly focused on retention of higher yielding customers whilst discriminating your typical flyer who only travels once or twice a year on a low budget. Explain to me how that one is fair!?
