Almost everything on David Owen's airline costs $50.
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.
If you and your spouse are dressed almost identically, or if you are carrying your passport in a thing around your neck, or if you are wearing any form of footwear or pants that you clearly purchased specifically to wear on airplanes, or if you make it obvious (by repeatedly turning around and talking to passengers in seats not adjacent to yours) that you are travelling with a group, the charge is fifty dollars.
