My TPs used to be 95%+ on BA metal and 100% on BA tickets, and it was under those conditions I first gained GGL flying in W.

Over the last few years I have managed to get my employer to cover J where it is reasonably priced, and so have moved most of my eastbound work travel to QR, hence even though my total amount of travel has declined quite considerably, I've managed to maintain GGL but at the same time the proportion of BA metal and/or BA ticketed flights has probably dropped to somewhere around 20%.
