I have used *Alliance for my trips to India after Oneworld disappeared from Canada.( more or less) I have had no problms getting award seats on TG to BKK via Pacific and onwards. But TG J to BKK is 100000 points and to India is 185000. So I try get the award to BKK and buy a cheap ticket to India. Works all the time. Also, If so desired you can go TG through Europe and connect with TG to India without any big problems. SQ is harder to get awards (except Y) and LH seats are frequently available. So the choices ( award or otherwise) are better with *alliance.
