Connect with old classmates, chat with friends...now book flights on Facebook.

Delta Airlines added an application to its Facebook page today that allows customers to search for flights, book them and share them with friends without navigating away from the Facebook page.

For the first time, it seems an airline has taken customers' Facebook interaction with air travel to a new level. Delta and other airlines have fan pages on the social networking site, but the new Delta Facebook app is just the beginning of the airline's expanded marketing plan that intends to be more user-friendly and interactive.

“Our customers are spending more time online and are looking for new ways to connect with us,” said Bob Kupbens, Delta’s vice president of eCommerce, according to the Atlanta Journal-Constitution . “We’re now delivering technology where our customers are.”

The airline posted a message on its Facebook wall earlier Thursday announcing the new Delta Ticket Window, which can be found in a new "Book a Trip" tab.

According to the AJC, Delta also redesigned delta.com and will be introducing an iPhone check-in app, as well as other methods for purchasing tickets on sites other than delta.com.

“Unlocking the full power of social media and mobile apps is the next step for Delta,” Kupbens told the AJC.
