Thank you for your help

1. I don't fly enough to get frequent flyer perks from any airline. Usually I always travel economy class and that is what I'm planning.

Seeing Copa's rates for business class, I am considering that however.

2. I think 4-5 days in Rio and then several days elsewhere in Brazil. The plan is Rio first and then tour, but that could be reversed if there is a good reason.

3. As much as I would like to see more of Brazil (and also visit Argentina and Peru) for this trip 2 destinations is enough. Given the limited time and money I would rather slow down and enjoy those 2 locations rather than rush to get to the next.

Thanks again. I'll reply again tomorrow with some questions - very late here
