You mean it's not already?
Public conveyance is course enough with foul mouthed passengers, unruly brats inflicting torturous behavior that would be banned at Gitmo, and horribly talkative or inebriated (or both) seat mates with bad personal hygiene.
All this for sky high ticket prices and interminable security queues. And now, pocket pool pervs watching in-flight porn?
What the heck. The airline industry is only hemorrhaging money & customers.
Note to Management: Check out the survey which says NO PORN!
