The following Airlines are CAA appoved to offer MCC with Type Rating Conversion Courses.
Air 2000
Atlantic Airlines
Britannia
bmi
British European
KLMuk
Monarch
TNT
I would assume that there are actually a lot more, however my info is slightly out of date. It would follow that these Airlines do not require MCC as employment criteria because they provide it. This is probably not the case though, as removing applications without MCC is an easy way to create a smaller pile of CV's on your desk.
As mentioned in another thread....Yes MCC is a sham.
