frankfurt cowboy,jet2 probably have as many experienced/unexperienced pilots as any other airline,and there are plenty of other airlines useing "geriatric" aircraft,so until they start dropping like flies i would'nt worry
smudge @ all r.e. the bogus engineer, i remember reading some where that the guy poseing as an engineer only had a ppl license,he also allegedly worked for another airline at the same time working different shifts,he said something like his license was still being processed by the caa.so it was'nt only jet2 that were duped by him.
