We flew Song out of Hartford, CT to MCO in March. LOVED IT!
The flight went by so quick - between the music trivia game, the tv, and the music. My only suggestion is that you bring your own headphones. They give you little headphones that you stick in your ears...which tends to hurt your ears. So for the ride back, I bought a $5 set of headphones, and was glad I did. Any headphones (like for walkmans, etc) will work.
Have fun.
