Summer is coming! What are some apps you use to plan / book vacations?

Though this app won't help you much with planning your trip in advance, it can be of great assistance if you are travelling, and, more specifically flying.

You can track yours and others flight status in real-time, see constantly updated flight info (whether it's late or on time, etc.) get airport weather and schedule info, aircraft type and age, etc.

The information this app provides is pretty accurate, its interface is simple and easy to use. Also, it's  free.

Reveal hidden prices. They claim this - "We're better at finding cheap flights than anyone else— so good, United Airlines actually sued us for it". Skiplagged 2 [New version]

They show hidden city ticketing trips in addition to what sites like Expedia, KAYAK, and Travelocity show. Taking a stop might save hundreds of dollar as @melaniepinola mentioned here - http://lifehacker.com/skiplagged...

You can also track previous searches for changes in price. Available on iOS/Android.
