Which Airline App

By Chris Morris

PHILADELPHIA (CBS) - On today's APP-tastic and Outta SITE - Which Airline.

Road warriors are always on the lookout for the lowest fare and fastest flight. WhichAirline is a new app that aims to compete with some of the larger travel sites, by offering comparison shopping from low cost and legacy carriers as well as online travel agencies.

That's especially useful if your travel will take you through Europe, which has a higher density of low-cost carriers.

Check out the WhichAirline app.
