You must be careful using this site. Here is what I know. When you visit the website and search for a flight the prices you see are the best prices for the current travel year not for your travel dates. When you book a flight with them for a given price you will receive a confirmation number, but here is the kicker, your price can still change as it did for me. They raised my flight price by $600 after I got my confirmation number and to top things off I had to call them to find out this was going on. They told me (I am not listing their names since the workers are subjected to the company policies) that your ticket price can go up after you receive a confirmation number and have paid. I have traveled on planes for 40 years and never have my prices increased after getting a confirmation number. So again, I will say be careful using this site as they can quote you any price to lure you in and then increase the price after you commit (pay and get a confirmation number).
