Simon Chowder,
In relation to your post there is a big pay gap between Engineers, Pilots & ATC to dispatchers/handlers/ tug drivers check in staff etc etc etc.
Theres is a bloody good reason for this. When you have spent thousands on becoming a pilot, years becoming an atco or sat over 12 exams to become an engineer, where any 1 little mistake by any of these people can cause death then its hardly surprising there is such a gulf in payscales...........
