I'd like to book this ticket:

How do I go about since it's two carriers on two alliances?

Anybody have an idea how fares for this route will be in a few days? (I'm flexible on dates, any time to complete travel by the 4th from June 19th...) I'm surprised it went up so much already; usually these fares are 200 rt...
