Hipmunk takes the traditional flight-search model and turns it on its head, showing flights sorted first by “agony,” then by price and other factors. You’re treated to a grid of at-a-glance info about which flights have Wi-Fi and which have long layovers, all in a fun, easy to use interface. The app finds hotels based on location, too, and pulls in reviews from TripAdvisor. You can even start booking a hotel from your phone and then finish up the reservation on your computer.
