In September of 2011, Google introduced its Flight Search service. The service provides information on upcoming flights to specific destinations, providing schedule, price, and airline information. Now Flight Search has become iOS-friendly, perfect for those who want to check on flight availability and pricing on the go.

What Google did is to make Flight Search fit the Safari browser on the iPhone, iPad, and iPod touch. The features of Flight Search include searching, discover by location, filtering results by price, flight time, airline, and calendar view.

One little trick I found is that you can use Siri to call up Flight Search. Just tell Siri to "Google flights between Denver and Las Vegas" (or whatever two points you're interested in flying between), and one of the top results that Siri will produce is a Flight Search listing. It's a fast way to get a first pass at flight schedules and pricing while keeping up your personal relationship with Siri.
