Once the air carrier determines the availability and pricing of the different itineraryfare classes of the different flights, a distribution channel is needed to link the product to the potential customers. Ticket distribution channels are the media through which air carriers share travel information, including available itineraries and prices, to their prospective customers. Generally, the ticket distribution channels are classified into direct and indirect. In direct distribution, the air carriers make direct contact with their customers for ticket sales, and no intermediaries are involved in the sales process. With indirect distribution, intermediaries are involved in the sales process between the air carriers and the final customers.
