A deposition is one of several devices used in the discovery phase of litigation. It consists of one or more attorneys questioning a witness, under oath, with a stenographer who records the testimony. A judge is not present.
As of publication United, Delta and American Airlines charge $125 for flights in the United States and most international flights in North America; Spirit Airlines charges $100 for domestic flights; Southwest requires payment of $75 for each in-cabin pet; and AirTran's pet fee is $69.
Southwest is great for indecisive travelers. Other U.S. airlines generally charge between $75 and $150 for most changes to an award ticket, and between $75 and $200 to redeposit miles after canceling an award flight. But Southwest will allow you to change your ticket for only the difference in cost of the new flight.
