    You left out the most important apps: either Kayak (with Kayak Trips) or TripIt (I use TripIt Pro). These let you track all the steps of your trip and send you text messages with flight status, gate changes, etc. Also, I would recommend Yelp over UrbanSpoon any day. I like their reviews and ratings, plus their “Nearby” feature does a good job of balancing ratings with distance from where you are.

    all apps rather americo-centric. Just sayin
