Crewboi, Jet2 is not a relatively new airline, only the idea and paint scheme are three years old. Everything else, including management, aircraft etc. are Channel Express. And the "old aircraft" idea comes from the original 737QC purchase, based on low utilisation at night on cargo flights and the odd pax charters during the day. So my guess is that it will be a good few years before we see Jet 2 ordering brand new aircraft, after all the management team (PM) has not changed from the freight days and to be fair, they are making money. So why saddle themselves with huge debts for new aircraft?
