There is an interesting argument that goes...
... if it costs £X million to recruit and train a pilot and we are getting Y years service out of them on average before they disappear off to the airlines, and we want some of them to stay on for another Z years, then anything less than X/Y per year is a bargain. Hmmmm, if you believe the blurb that it costs at least £3M per pilot and we get 16 years out of them (which we don't!), then the financial argument says anything up to £187500 PA is a good deal, especially when the crews are already effective, don't need to do 3 years training/holding/growing up...
Not that I think that is a good idea....
