Airline seats are designed for someone who is 5 foot tall and weigh about 100 pounds. However, there are ways to make the most of your confined seat time.
Sit in the wrong seat, when someone shows their ticket with your seat number, say the airline must have double booked. When they ask to see your ticket, get defensive and say that you know how to read. Once you see that your seat row and letter are completely wrong, say that you must have been thinking your connecting flight.
Leave the armrest up and ignore the fact the flight is overbooked and someone is bound to sit beside you. Grumble and fuss with irritated noises when someone comes to claim their seat, especially if you are on the end row.
Recline back as far as possible, and check the recline position every 2 or 3 minutes. Wait until the person behind you begins using their laptop, check to see if your seat will recline further while shoving the tray table into their gut.
When drinks are being served and someone is happily munching on pretzels and sipping ginger ale, check your seat once again causing their refreshments to move about the cabin.
