Most of our training is done on-job.
And let's be honest - so is ours.
In terms of the service, we're taught next to nothing 'in school'.
And even after safety training, which is somewhat regimented, things seldom follow the ideal course of action taught in Cranebank.
I agree with you in that I don't want to get into a tit-for-tat chat about whose job is more/less important/menial, but along with our pilots, I think ours is perhaps the ONLY job where the actions you take in a split second during which you're under immense pressure can have such a major impact.
And I think it takes years of flying to feel truly confident that you can handle these situations.
As a former travel agent and ground-volunteer (during snow), though, I'd agree again that getting a plane in the air is an effort from a team far, far deeper than the cheaply produced pin-striped uniform.
