At least given the initial research I have done, I think the answer is no, but I thought I would ask anyway.

Is there anyway to get all the way to Phuket (from the US) on OneWorld.

All the options seem to be either *A (ie Thai, Austrian and Singapore) or non-aligned like DragonAir.

Any ideas?

I think my best bet is probably to fly to BKK and then just pay for a Thai flight.
