I have been to several sites to book my international flight, and Cheap flights was one of the easiest to understand. Almost everything that I wanted to know was right there with the flight day and cost. I thought I was early, looking to buy tickets a month and a half out, but in Vietnam it will be over the Tet holiday, and the last leg into the country was heavily booked. As an infrequent traveler, the only information that kept me from making this five stars was information on getting from one airport to another in Tokyo, Japan. That information would have taken away a little anxiety that I have on such a long trip.
