The QF site is particularly bad in this respect. I have just been nailed with the difference between full economy and full economy. B and H fares are full economy miles and discount economy status. All I wanted was the status points, stuff the miles. Now I have wasted hundreds of dollars on the higher fare groups. OK, it is my fault but the difference is not exactly clear. Just to confuse me further, on a BA EC card, then YBH is full economy for both status and miles.

I think that W is the full WTP fare and T is the discount fare. You had better check this carefully but I have not heard of T fares being considered as anything other than WTP elegible for awards.
