Also, find someone in an upper class a few times and ask them. They will be able to provide great insight throughout the flight if you ask them to. They can let you know you are sneaking in or out throughout the flight LONG before you might, and it will really help your flying. After you do it a few times with them, you will begin to recognize some of the similar signs. I've always enjoyed calling for guys in the lower classes. You can really be a great help if its done right.
