Any airline having medical requirements which exceed the minimum requirements should be applauded.
I'm a class one medical holder, my AME (a senior hospital consultant) offers extra tests at minimum cost and not so long ago one of these tests picked up the start of something which could have had serious long term consequences on my health. Fortunately I was able (with the considerable assistance of the medical profession) to do something about it and it's no longer a problem.
I know that technically, you're only "fit on the day" of your medical, but there's much to be said for going beyond the minimum requirements, for your own interests if nothing else.
