The airline industry, like any other, has a specialized dictionary. These are words and phrases that are used commonly by airline employees for which the meanings may not be obvious to outsiders.

At great personal risk on an undercover sting operation, I was able to procure this dictionary. Now I present it to you with no thought to my personal safety in the interest of academic freedom.

Remember folks, “If it ain’t Boeing, I ain’t going!”
