Thanks for your replies guys. I have to confess I do know Andrew and Julie or rather I did. About 12 years ago I worked for them. I attended a few seminars and chatted about airline safety as I had been involved in a incident myself.
I just remember they seemed to be advertsing everywhere and up until a couple of years ago I haven't heard a thing.
Personally I would say steer clear of companies that do offer these one day courses. You can learn as much from someone that actually flys as cabin crew as you would from attending one of the courses and save yourself quite a lot of money in the process!!!
