Seth Kugel, the self-declared “Frugal Traveler” of the New York Times, wrote a piece comparing old and new travel sites, including my favorite, Hipmunk. I love Hipmunk for its visual interface and it’s ranking of flights based on its “Agony Factor” (a combination of ticket price, flight duration, departure, and arrival). For all you travelers responsible for booking your own trips, this article is worth a look. Once you’ve booked your flight, don’t forget to forward your itinerary to Tripit (as I covered in this entry).
