10. Ditch your baggage

Ease your travels — and possibly avoid extra baggage charges — by mailing your suitcases, Bergman said. Try old standbys such as FedEx and UPS or a baggage courier service. Some cost more than the airline fees, or tack charges on top of those fees for a hefty final price.

But if you are willing to send bags a few days in advance, you might be able to save depending on the weight of the bag and the distance covered. Even if not, sending bags can make airport travel less aggravating, which can be priceless.
