I'm not sure what the total number of bmi regional employees is, but there are about 170 pilots, I'm guessing about 150 cabin crew. There are also office staff in Aberdeen and an engineering base there, but many of the other admin and support functions are carried out collectively for the bmi group so it's hard to be exact. My estimate for bmi regional staff would be around 500 but I could be out by about 100 either way...
