Thanks for the advice Dave.
I don't know much about BA WT+ fares, other than that they're more comfortable. I remember reading that I can upgrade those BA segments on a ONE fare for a small fee... it would certainly be worth it to me since I'm 6'2" and 110kg. I was really planning on dodging all BA coded flights because of the crappy 25% accrual policy. Is there written documentation somewhere about WT+ getting you 100% miles?
Cheers.
