I'm now studying in Indiana, USA. I would like to go back to Hong Kong after the spring semester in May, but I have to visit Stockholm, Sweden for a conference in July. After that probably I will go back to the States.

What would be the most inexpensive way to go for my trip?
It seems that IND --> HKG --> Stockholm --> IND is the "smoothest" way but i don't know how much would it be and how to book a trip like this...
