I do not actually see anybody having a dig at Jet2 for "being late all the time", nor is it any sort of constructive critiscism, merely remarking about their forward planning leasing in the ZAP 757, which I think is positive comment. Perfection does not exist in the airline industry, or in avaition as a whole.
Things went badly for EZY the other week through no fault of their own, so they raked up 2 spare 737's from Luton and sent them up to Newcaslte to cover late flights, a lot of praise was passed EZY's way via this forum. I think this could be the status quo in future. I, as well as many pruners remember the days when a Dan Air 732 went tech then that was it - flight cancelled..... catch the same flight next week if there is room!
