If you're a frequent traveler and Expedia customer, you might benefit from becoming an Expedia+ member. You'll get access to members-only deals and bonus offers every time you shop with Expedia, and earn redeemable points for every dollar you spend on the site. You can use your points to book travel for yourself or anyone else, or you can donate them to St. Jude Children's Hospital and help fund research in the prevention, diagnosis and treatment of childhood cancers.
Expedia also offers a best price guarantee which covers virtually every part of your trip. If you find a cheaper identical trip withing 24 hours of booking, they'll refund you the difference and give you a $50 Expedia gift card.
