Another idea is to have the phone numbers of booking agents, customer server representatives as well as car rental companies and hotel lodging already programmed into your cell phone, just in case. And with so many airlines charging upward of $100 for checked baggage, it is important to pack wisely for any holiday trip. You can save money by cutting back on what you bring with you and check into the safety regulation for baggage handling. Even the most meticulously wrapped present might have to be opened by the airline as a safety check.
