So, here's what I go so far using miles.

IAD-NRT-PEK on ANA in C.
SIN-NRT-IAD ANA in C.

How's ANA's service in Business, never flown with them.

I decided due to the limited avaliability to reroute myself to visit Bangkok and Singapore instead. So now I am trying to purchase a ticket (not award ticket) from PEK-BKK, BKK-SIN and SIN-DEL.

PEK-BKK was $654 per person on Thai Airways, seems high, any suggestions. Maybe I am just booking too early. I did find BKK-SIN on Jetstar Airways for $99. Also, any suggestions for SIN-DEL RT. The cheapest so far Jet Airways for $526 per person, was hoping to go on Singapore or *A member.
