Cheap Air Ticket on Domestic Flights at Lowest Airfares

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. A ticket is made up of one or more flight coupons. In the old paper ticket system, these flight coupons were the actual tickets that were used for travel. One flight coupon was used for each leg of the flight.

The carrier is represented by a standardized 2-letter code. In the example above, Thai Airways is TG. The departure and destination cities are represented by International Air Transport Association airport codes. In the example above, Munich is MUC and Bangkok is BKK. The International Air Transport Association is the standard setting organization.
