But remember you are limited to two stopovers in Asia, so CAI might be a better deal if you are wanting additional stopovers. Then you could do:
LHR-BOM-BKK-SIN-CGK-HKG-NRT-USA
You can also avoid an expensive addl segment charge by open jawing bkk-sin. You should be able to get a oneway ticket for under $200 and probably closer to $125 if you search.
