Correct! In the course of one day, I can end up dispatching/turning around a Dash8, then a 737-300, then a BAe 146, then a 757-200, then a Fokker 100, then an A320, then a 737-500, and so on.
Good fun that way. Saying that CPL/IR holders and the odd plane spotter in the job are helping the wages to stay low is nonsense; what keeps wages low is competition between handling agents to offer the same level of service to the airlines at the lowest possible price. For instance at BHX, all three of the main handling agents (Aviance, Servisair/Globe Ground and Swissport/Groundstar) pay the very same (poor) rates of pay
once basic salary and shift pay are taken into account.
