LINK If you're planning to fly for the holidays, don't wait to buy your ticket. Procrastinators are going to pay an even higher penalty this year if they wait, CBS News travel editor Peter Greenberg explained on "CBS This Morning." The Wall Street Journal reports Thanksgiving week flights in the U.S. and the Caribbean cost 9.4 percent more than last year, and Christmas week fares are up 7.3 percent. Greenberg explained price for holiday air travel also depends on when you want to fly. He said, "If you want to fly the Wednesday before Thanksgiving, remember, they made a movie about that. It was called 'Planes, Trains, and Automobiles' with John Candy and Steve Martin. If you can, try to fly out on the morning of Thanksgiving, and don't fly back on Sunday. You'll pay higher rates again. Try to come back on Friday or Saturday when everybody else is at the mall -- and you'll get a 10 percent reduction in fares."
