Long time lurker - first time poster. Although mere PAX and a frequent user of various European airlines due work, one thing I always find alarming is the practice (mainly on LoCos) of tagging cabin bags for the hold at the gate - whenever I witness this I seldom see any effort from gate staff to check whether any potential Lion nasties are removed from what is now effectively checked baggage. If something similar to what befell KL809 above, was to happen in someone's checked bag, couldn't the results have been far worse? Sometimes I wonder if this isn't the 'next big thing to go wrong' and whether it will take the loss of 000s of lives before something is properly done.
