I have been in BA for 15 years, 11 of them LH and apart from never having heard of the scam you mention I have rarely witnessed anybody reporting sick downroute except for very valid reasons, in fact it is something that is done with marked reluctance. Good story though.
If you care to take a step back do you really think that the majority of BA pilots are any different from pilots in any other airline? Most of us have the same morals and concerns as anybody else.
A final point, getting called from standby to go to HKG would not attract anything like £3000, not even close!
