Loadmasters
I was a Cargo / Passenger Dispatcher at a large international airline for 15 years. Cargo: just B707 and B747. Passenger: TRI; B747 (+combi); B777; B767; B757; B737 well - all the B's actually....... and the Concorde. (Doh - just gave the game away).
Went through the "grouind-up" method but started at Reservations instead of Loading. My experience was that loaders rarely become planners / Dispatchers. Load planning was fun but that was before fully computerised stuff and ACARS etc. created greater productivity, but with a lower enjoyment factor. Dispatching was the best job.
Flew as loadmaster a few times but that was on exceptional special flights. Anyway. Enough about you - let's talk about me...
Recommendation: Get a job with an airline and then network like mad.
