Expedia.com - What You Need To Know
I personally have used Expedia coupons on many occasions to book airline tickets for my family. I have almost always found Expedia to come in with a lower rate than their competition. Not sure how they do this but they must have an agreement with the airlines, especially on last minute travel. The airlines don't want any empty seats so they are willing to let Expedia sell them at a discount to get people in them. I have not used Expedia to book a hotel or rental car yet, if you have any experiences in this regard email me so I can post them on this page. I'd like to create a review section for Expedia.com.
