Hey guys.

I'm going to San Francisco (SFO) for three months this summer (from BGO, Norway, ultimately going back to KRS, Norway), from early June to early September. Should I book my ticket ASAP (return ticket is starting at around 1100 USD at the moment) or is it likely that the price drops in a few months?

I'll probably have to use KLM/AirFrance/Delta or SAS (or perhaps Icelandic Air that still offer two checked in luggages on Economy on transatlantic flights), as not many carriers offer flights to the US from these not too big Norwegian airports.

Thanks a lot
