When you buy an airline ticket, do you know the terms and conditions you’re agreeing to? Better read the fine print.

The “contract of carriage” is a lengthy agreement that covers everything from A-to-Z about flying the friendly skies, including your personal behavior.

As it turns out, the airlines can kick  you off for just about anything, including how you smell!

What’s in the contract of carriage?

In its contract of carriage, Southwest Airlines states that it can refuse to transport or remove a passenger for the following reasons, which are listed under the umbrella of "comfort and safety."

  1. Persons whose conduct is or has been known to be disorderly, abusive, offensive, threatening, intimidating, violent, or whose clothing is lewd, obscene, or patently offensive.
  2. Persons who are barefoot and older than five years of age, unless required due to a disability.
  3. Persons who are unable to occupy a seat with the seatbelt fastened.
  4. Persons who appear to the Carrier to be intoxicated or under the influence of drugs.
  5. Persons who are known by the Carrier to have a communicable disease or infection and whose condition poses a direct threat to the health or safety of others.
  6. Persons who have an offensive odor, unless caused by a disability.
  7. Any person who cannot be transported safely for any reason.

It's up to the flight crew to make the call about removing someone from a plane. Passengers who are given the boot should get a refund, CBS reports. However, unruly passengers can face fines and even prosecution.

Each airline has a different contract of carriage, but many of them are very similar. You can find a copy on your carrier’s website.
