Jet2 and Ryanair are a very different kettle of fish and even Easy is
An example... Charter airlines make money from the holidays, scheduled airlines make their money from the flights. EZY don't have to worry about unfilled hotel reservations and don't have to worry about handling teams sitting around doing nothing. At the moment it would appear that holiday packages are very popular and will subsidise any inefficiency in the operation such as self handling, EZY have an advantage in ground handling expenditure in that they have more non based arrivals than Jet 2 which guarantees greater utilisation of the ground handling assets during the day. Jet 2 on the other hand have very few non based arrivals meaning that once the early departures have left, the handling teams are under utilised until the aircraft arrive back in the afternoon, and the same applies after the lunchtime departures have gone, the handling teams have nothing to do until the lates come back home. EZY balance departures and arrivals over the course of the day and share their handling agents with other airlines which means their handling costs are lower. IMHO, I think EZY are better placed to weather a downturn.
