I want to book a flight from Denver, CO to anywhere in Bolivia using some of my 160,000 Chase Ultimate Rewards. I'm told that Chase uses Expedia to book flights. It's as if Bolivia doesn't exist on the Chase or Expedia travel site. I can book flights from Denver to Bolivia through other sites such as Kayak, but I can't use my rewards points that way. I called Chase & Expedia to ask why no flights were available and got a variety of answers from it's a problem with my computer, to civil unrest, to they don't contract with airlines from here to there. Does anyone have insight into how this works? Is Bolivia really an "excluded" destination, and if so, why? Is there any hope of me getting all the way to Bolivia using my points?
