Handling agents have been in a race to the bottom for years, slashing costs and wages as the airlines demand more for less every time. It can go massively wrong if you need a decent level of service though, Virgin dropped Swissport Gatwick and BA had to take their outsourced LGW ramp operation over (albeit with the same people they used to employ) as GGS when Swissport dropped the ball. Indeed Ryanair did the same at STN with er....Swissport. Running theme there maybe, bottom line being there's loads of zero hour contracts and no contingency when things don't run to plan. Blame the airlines, who blame the market for expecting something for almost nothing. It makes the old Servisair look like a gold plated superstar by comparison.
