bealine, the thread subject referred to the airline, not the people who work within.
One knows the head Customs fellow at a reasonably large airport and he says some of the handlers make an extra £100k a year from the stuff they steal. His solution would be for the airlines to take more responsibility for the baggage entrusted into their care, but nobody seems to care enough to do much about it. Would cost them too much and their liability is limited by law/treaty , and that suiits them just fine.
