I just flew Song from Bradley to Tampa last week. It was a wonderful experience. The flight was on time, the flight attendents friendly and the extra bit of room was great. We didn't luck out on getting the planes with the TV's, but they should be installed on all their planes by the end of March, so they say.
I've decided Song is now my favorite airline as Southwest just won't do seat assignments and I find it much less stressful knowing I have an assigned seat so I don't feel I have to rush so much.
One of the flight attendents mentioned to us that the new CEO of Delta isn't sure he wants to keep a separate airline within an airline, so if we want to keep Song flying - let them know how much you like them! I sent an email to Song(on their website)to let them know of my positive experience.
