So, let me get straight on this.
A "chap" from jet2 calls up and asks if you'd like to attend an "information day" some time soon.
The answer is "NO, I WOULD NOT".
What can they possibly tell you about the company? Nothing, I would say.
What can you (or we as a group) tell them about us as pilots by agreeing to such a spineless, non commital offer? Loads: in fact just how low you (we) will stoop to sit in a jet.
Get serious. Jet2 are a professional outfit, testing the market. They know what they want: cheap pilots.
Don't be a fool.
