Having just completed the MCC with Jetlinx, I'd like to report back to PPruNe that the course was absolutely top notch. I'd have no hesitation on recommending the course.
I know the objective of the MCC is to learn about the multi-crew cockpit environment, but to be able to do that in a full motion B757 at BA Cranebank really made the whole experience a lot more enjoyable. I know the cost is a tad more than other courses, but IMO it was worth every penny.
3 of the instructors that taught us were all ex-RAF with a vast amount of experience in both military and civilian flying and I felt they pushed us above and beyond the MCC syllabus.
If anyone is considering training with Jetlinx, give me a pm with any questions you might have and I'll try my best to give honest and accurate answers.
