As for the U.K.:
Have you checked the CAA site ?
http://www.caa.co.uk/publications/search.asp
You could also check with labour organisations, via:
www.cc89.org.uk
www.bassa.co.uk
or, perhaps even better, go directly to the company itself:
Dr. Sandra Mooney
Director of Health Services
British Airways plc
Waterside
PO Box 365
Harmondsworth
UB7 0GB
United Kingdom
but I fear they may not be too keen to reveal such sensitive information.
Good luck and hopefully you'll report your findings here !
