Jon & Rush,
Guess most airports could do it with relative ease if enough resources (infrastructure space, staff & IT) were put into it.
But who pays? I can see the howl of protest on this site at the cost/tax introduced to enable this to happen; never mind the sniping at the staff who would do this.
In many, many, many years of airport ground handling I know that this event is, in real terms, very rare (I accept that if you are the unfortunate it is very distressing and frustrating). I would estimate that the incident rate is at less than 1% of the mishandled baggage rate which in turn is a very, very (even with the extreme recent publicity relating the LHR) low ratio - lower than 1:10,000 - of the total number of bags handled.
