Looks like Ryan messed up by waiting to exchange the currency on his flight out to Rio. The airport spot rate turned out to be the worst for Ryan as the Brazilian real had appreciated versus the US dollar over the year. The best exchange rate was that in January of 2016. But then again, Ryan did not have a crystal ball and did not know how the exchange rate would do over the year. Welcome to the dilemma of exchange rates in international travel -- and business.
