I need a one way ticket from Medellin to Miami on July 5 2011, where is the cheapest?

The price is about right since you are buying a one-way ticket and you are flying during the summer which is an expensive time to fly. I suggest you check out a href="http://www.kayak.com" rel="nofollow"http://www.kayak.com/a and contact a travel agent to help you. I think American Airlines flies to Medellin so you can go to a href="http://www.aa.com." rel="nofollow"http://www.aa.com./a
