David Owen writes about his airline in the New Yorker.
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. Flipping through the airline magazine or the duty-free catalogue in your seat pocket is allowed only while the aircraft is on the ground and other reading matter is temporarily inaccessible. You may no longer hum or do any form of beadwork. If you wish to attempt a Sudoku puzzle during the flight, you must demonstrate to my satisfaction that you realize that the nine spaces in every row and column must each contain a unique digit, and that the nine squares that make up the over-all Sudoku square cannot be completed without consideration for how they fit into the entire puzzle. Do you understand this? No? Fifty dollars.
Lucky that I am lousy at Sudoku. Heh.
