Xrayalpha, Hats off to you!
However, you are comparing chalk with cheese here. Most schools that teach for the PPL/A are still operating under the illusion that FIs will give their time for hours to get ahead in the queue for a commercial job. The reality is that a type rating gets you higher up the queue. Commercial Wannabes have cottoned on to this which has left many schools short of FIs.
As microlight hours don't count for group A qualifications, microlight schools have to pay living wages if they want to operate 7 days a week; hobby instructors are all very well but it's difficult to run a business relying solely on them.
I am sure that Group A schools will have to follow suit soon or go under.
