As in many businesses, over the years the airlines have developed unique meanings for many commonly used terms. This often leads to bewilderment of passengers simply wanting to get from one point to another without having to learn a whole new set of definitions.

So as an Err Travel service to those of you who may have some confusion about air travel terms, I offer the following definitions.

Cancellation n.
A mark on the back of your returned check and the simultaneous notice appearing on a television monitor in the passenger waiting area that you won’t be going anywhere today.

Carrier n.
(1) Something my dad used to put on our Olds to hold the tent for our summer vacations.
(2) A term used by my mother to describe a “bad girl.”

Carry-on v.
What my wife tells me I should seriously limit if I expect this marriage to last.

Charter n.
A person who makes charts. A job similar to a cartographer. (E.g., The charts prepared to show Congress that the airlines are indeed viable in spite of losing money for years and years were prepared by a charter.) [Not to be confused with a "Charo-ter," which is a Cuchi-Cuchi groupie.]

Commercial flight v.
A back-to-nature movement best represented by people who are leaving big cities with commercial blight for places such as Vermont where there are no billboards.
