Death Traps is a little harsh. Yes they are old but Jet2 have excellent engineering. FT is a fairly new addition to the fleet and probably hasn't had the Jet 2 engineering touch yet. Just because an aircraft is old doesn't make it a death trap. I own a 1984 aircraft and it is well looked after and has never given me a moments worry. New aircraft have problems too, heard of the 787?
FT is an ex BMW Baby ac and is only 16 years old which is young for a 733. Please be careful what you put on here a blanket statement putting down an airline like that could loose a lot of good people their jobs in the long run.
FYI the Privilege Style ac are not much younger than this ac. Jet2 take maintenance seriously they accept older ac have problems more frequently hence keeping spare ac available, Norwegian didn't think they needed to with the 787 and look what happened to them.
