Ever since the FAA decided to be more flexible about personal electronic devices on planes, things have changed quite a bit. Now, as an effort to make things even better for travelers, Delta has rolled out a new initiative called Delta Studio, which focuses on adding more in-flight entertainment options to its fleet. As part of this, the Atlanta-based airline revamped the Fly Delta app for iPad, and it now lets passengers use it to stream movies, TV shows and other media -- in addition to the destination info and interactive live-map view features that were already there. Delta Studio is free for Economy Comfort, First Class and international flyers; those on Economy, meanwhile, will also have access to stuff at no charge, but most of the decent content (like newly released films) is going to cost extra. Not surprisingly, you have to wait to reach 10,000 feet before streaming anything, since it does require an in-flight WiFi connection. Still, that's something you should be used to by now.
