Delta has introduced a new iPad app called Fly Delta



From Engadget:

The free app lets you do the usual stuff like checking-in and booking flights, but it also goes a few miles further. Aside from serving as a light travel guide, offering up info on your destination, the app will also serve inflight needs, like purchasing WiFi and other onboard amenities. What's more, "Glass Bottom Jet" offers an interactive live-map view of the world below you with social networking integration.
