An airline ticket is a document or electronic record, issued by an airline or a travel agency, that confirms that an individual is entitled to a seat on a flight on an aircraft. The airline ticket may be one of two types: a paper ticket, which comprises coupons or vouchers; and an electronic ticket The ticket, in either form, is required to obtain a boarding pass during check-in at the airport. Then with the boarding pass and the attached ticket, the passenger is allowed to board the aircraft.
An innovation of Google Flights is that it allows open-ended searches based on criteria other than destination; for example, a user may search for flights within a range of times and a budget and be offered various destination choices. Alternatively, a user can select a destination, and Google Flights will calculate every price for each day of the next 12 months, visualised in a graph or table. This allows users to easily spot the cheapest date to fly to the destination.
A ticket is generally only good on the airline for which it was purchased. However, an airline can endorse the ticket, so that it may be accepted by other airlines, sometimes on standby basis or with a confirmed seat. Usually the ticket is for a specific flight. It is also possible to purchase an ‘open’ ticket, which allows travel on any flight between the destinations listed on the ticket. The cost for doing this is greater than a ticket for a specific flight. Some tickets are refundable. However, the lower cost tickets are usually not refundable and may carry many additional restrictions.
Only one person can use a ticket. If multiple people are traveling together, the tickets are linked together by the same record locator or reservation number, which are assigned, if the tickets were purchased at the same time. If not, most airlines can cross-reference the tickets together in their reservation systems. This allows all members in a party to be processed in a group, allowing seat assignments to be together
