I'm new on here, so bear with me. I'm sure this has been answered somewhere but I can't seem to find it. I have a lot of Mileage Plus miles that I want to use to fly to either Central or South America, which Continental covers well. I know you are supposed to be able to use United miles on Continental, but I can't figure out how. And on that note, I saw that a flight to Panama City was only 35k if you're using Continental miles, so would it be the same amount if you are using United's? Thanks for the help. And if this has been answered somewhere, I would happily take a link to that.
