Often the no frills airlines will charge less for a checked bag than a carry on. That is one place where you can save some money. If you can share a checked bag with someone else in your party and not pay for two carry ons, you might save a significant amount. My husband, daughter, and I will sometimes share one big suitcase and not buy any carry ons! Keep in mind that there are weight limits for checked bags, check with the airline to see how heavy it can be.
