I found an extremely helpful article in the June 2011 Westways AAA magazine about saving money on traveling. Now that airlines charge you your first-born for a checked bag, I am all about carry-on luggage only. Then, you don't have to worry about your bags getting lost, paying the fees, or waiting for your bags at baggage claim.
These tips come from Paul Lasley and Elizabeth Harryman of Westways magazine.
1- Chose colors that can mix and match easily.
2- Pack only 3 or 4 plain shirts that can be dressed up with accents (jewelry/scarves).
3- Wear something on the plane that you can wear again-- something a little bulky that will relieve space in the suitcase.
4- Wear your heaviest shoes on the plane and pack only 1 or 2 more pairs.
5- Plan on washing your clothes.
6- Think layers.
7- Don't take anything you don't need.
