Planning a Trip: Kayak
Kayak is as close to a one-stop travel planning app as you'll find. It makes searching for flights, hotels, and rental cars supersonic fast. The app doesn't offer all the filters of Kayak.com, you can, however, narrow results in key ways. Example: You can filter flight results based on airlines and airports, number of stops, takeoff and landing times, and price. You can also set airfare price alerts for a specific itinerary and create a price alert for any dates between two locations. Kayak makes good use of an Android tablet's screen, with filters on the left and search results on the right. And true travel geeks will love the apps' Flight Tracker feature.
