Staring blankly at the seat back in front of you for the entire flight is no longer permitted on my airline. If you have brought nothing to read, a book will be provided for your use, at a charge of fifty dollars.
Laughing out loud at anything in any movie, whether it is playing on the cabin system or on your own DVD player, is fifty dollars per incident. Asking me to turn off my reading light so that you can see the screen better: also fifty dollars.
I realize that you have a choice of airlines, and I encourage you to exercise it.
