Of course there are. The Light-fingered baggage handler for starters. The sticky-fingered Raffles of the conveyor belt need not fear discovery if everyone's bags are lost. He can just take their pick of the choicest items safe in the knowledge that there's almost no way he could be caught in the current chaotic climate.
The other big winner is of course the auction optimist, that panglossian Lovejoy who buys unopened cases (cases that still technically belong to some unlucky traveller somewhere let's not forget) at auctions which further boost the profits of the very airlines that claim to have 'lost' these cases.
The final big winners of the sketch , of course, are clever souls like you and I who never go on holiday, and therefore never lose our stuff, so we can enjoy a long and loud chuckle at all the baggage burglars, hapless holiday makers, and Samsonite gamblers involved in the whole sorry business.
