In a world in which this type of behavior has become all too commonplace, we are compelled to issue the following Air Law:
AIR LAW 18: No air traveler shall elevate their bare feet onto the bulkhead or above seat level for any reason during flight. Those found in violation of this Air Law shall be assigned seats next to the rear lavatory on their next ten flights.
Women travelers are exempt from Air Law 18 on a case by case basis because their feet generally don't stink...except when they do. Air Law Marshalls are instructed to utilize "thoughtful enforcement."
