CWS - though not for TP addicts, my fare to SFO came out at <£250, which even after the positioning flight on Avios works out favourably. I found ex-GOT accessed O class inventory, whereas ex-LON only wanted to sell B at £1k.
Sometimes, we gotta go in the back. Nice way of doing it. Upgraded the return to T class for ~£440 return all in. Not too shabby... Currently sat in the North Lounge with BOGOF Tatt - "how many do you want?" "I'll give you two". Superb.
