puerto rico: I'm looking to travel to Puerto Rico over winter break (sometime between Dec. 11 and Jan. 5), what is the cheapest way to get there? I'm looking for flights from either Chicago, Cleveland, or Milwaukee. (I live in one state, go to school in the other.) Thanks!|||That is high season in PR, meaning it costs more money. Alot of tourists come at this time & also people viditing family for the holidays. Try all the cheapest travel sights like orbitz. Use flexible dates & try to get one with a stop or two for lower prices, also if you cans search with nearby airports. & buy early!|||Bike and Swim? check out yahoo travel and see what flights are cheapest from where and when.
