I am planning a vacation to Koh Samui from SFO thanks to the HH deval. Anyways I was thinking of adding a side trip to India as well. About 4-5 days in India, 2 days in BKK and a week in Koh Samui (USM?).
What should the routing be? Should I book SFO-BKK-DEL and BKK-USM separately or book SFO-BKK-USM and BKK-DEL? Does it makes any difference? US Airways award chart is 30k for business for both BKK-DEL and BKK-USM
