Facelookbovvered makes a good point about Jet2 and it's clapped out aircraft.
They seem to have a policy of not replacing parts like they used to and this has affected reliability. Pax get f**ked off with diverts, tech delays and being bussed all over the place along with high fares. There'll be no customer loyalty if Ryanair starts dropping their fares after moving in.
Having a large fleet of ****tip 737-300s leaves PM with limited funds to buy a decent fleet of new aircraft
