I want to fly from BOS - SAO Mid October and then from SAO -LAX at the end of November. I have 100,000 Miles to use and I'm a total newbie about using miles so if anyone could help me out using them for the trip I would be extremely Grateful.

Also, while in Brazil I also need to fly from SAO - REC a few days after I arrive, then back REC - SAO a few days before I leave. If anyone has any ideas about using the miles for this that would be very helpful. Thanks so much for any help you can provide.
