Like i have said, easyJet do not give refunds for delayed flights! You pay for a flight to get you from A to B (MAN-AGP in this case), whether it is delayed or not, it does not matter. The only thing they do provide, is a Light Refreshment Voucher (LRV) per passenger after a certain number of hours. This is valued at £3/€4.50.
Companies do not cancel flight just because they want to. Crew obviously wasnt a problem if the plane was fully boarded.
