An airline itinerary can be obtained directly from the airline's website or by speaking with a reservations agent from a local travel agent or from an online fare finder and travel booking source. In most cases, it is not necessary to have an existing reservation.
In order to obtain an itinerary for a specific flight, it is necessary to know the date of travel, if traveling one way, or dates of travel if returning to the point origin. The point of origin and destination are also required. This information, once provided to a reservations or travel agent or input into an online booking source, can be used to provide flights that fit the travel criteria as well their availability. Details provided include the name of the airline, the flight number, the time of departure, stopover locations, the length of the stopover, the connecting flight number and the time of arrival at the final destination. In some cases, additional information, such as whether meals are served or the number of seats currently available on the flight, is also provided. For travelers who have already booked a ticket, this information can be obtained simply by contacting the source from which the ticket was purchased and inputting the confirmation or reservation number assigned when the ticket was booked.
