Well done and nicely putt I think you've covered just about all angles.
I think there needs to be a bit more control from the governing bodies, several enforcements to be putt in place ie 1/ a minimum handling charge 2/ a minimum (sensible) ground time 3/ and prehaps some control over how many handling agents at any one airport.
It may sound a bit harsh but it will help, you wont have handlers trying to under cut themselves just to get a scratch of work, loaders wont be breaking their backs to turn a 73-800 round in 20minutes thus reducing sickness, and finally the rumour of menzies coming into STN, there's only just enough work at STN to support the 3 agents at present.
All of this is of course is just in an ideal world, where the people who actually make the decisions come and have a look at an operation instead of just watching it on 'Airport' !?!
