What type of travel arrangement is typically not required to be justified when using City Pair flights?

City Pair flights are a fare structure used by the U.S. government to book travel for federal employees. Under this program, the government has negotiated specific rates for travel between designated city pairs, which typically do not require justification when booking. This means that when using City Pair flights, government airfare can be booked without needing to provide justification for the costs associated with it.

In contrast, other travel arrangements like personal travel, direct flights that may not be covered under the City Pair program, or chartered flights usually require justification due to their higher costs or differing purchasing criteria within federal travel regulations. Government airfare is specifically designed to facilitate easier and more cost-effective travel, which simplifies the booking process and eliminates the burden of justification in certain scenarios.
