As regard to Jet2 maintenance I have flown with them now for 2 years, very rare are there carried over defects, there are engineers at every base maintaining the aircraft EVERY night. Previously i flew for a well know flag carrier airline, the maintenance there was nowhere near the standards at Jet2, there were often yellow stickers everywhere with defects often deferred to the next hangar input etc (perfectly legal). The problem there was most of the aircraft nightstopped away from base and so there was no overnight maintenance cover, as a result the aircraft were in a very poor state. Jet2 currently does not night fly its 757 fleet and as so the aircraft are pampered. I cannot remember the last time i saw a yellow sticker with a deferred defect!
