Sorry haven't had time to read the whole thred,so I might be repeating whats already been said. They probably lost more money in the one diversion than they could ever hope to recoup by using min fuel everywhere. Thats the trouble with putting bean counters incharge of anything other than counting beans.
As far as publishing a league table, two things come to mind, have a competition to see who can come last, and, could this not be seen as harrasment and bullying. Its fine pointing out someones failings in the eyes of managment on a one to one basis but to publish it is a bit much. BA could probably save more money by not having to employ someone to monitor the fuel loads on the acft(that they don't actually fly on) than by having a draconian min fuel policy.
Whats next a league table for sick days, MORs, tech deffects, cups of coffee drunk on a flight.
