Airlines assign prices to their services in an attempt to maximize profitability. The pricing of airline tickets has become increasingly complicated over the years and is now largely determined by computerized yield management systems.

Most airlines use differentiated pricing, a form of price discrimination, in order to sell air services at varying prices simultaneously to different segments. Factors influencing the price include the days remaining until departure, the current booked load factor, the forecast of total demand by price point, competitive pricing in force, and variations by day of week of departure and by time of day. Carriers often accomplish this by dividing each cabin of the aircraft (first, business and economy) into a number of travel classes for pricing purposes.

A complicating factor is that of origin-destination control ("O&D control"). Someone purchasing a ticket from say, Melbourne to Sydney for $A200 is competing with someone else who wants to fly Melbourne to Los Angeles through Sydney on the same airplane, and who is willing to pay $A1400. Should the airline prefer the $A1400 passenger, or the $A200 passenger + a possible Sydney-Los Angeles passenger willing to pay $A1300? Airlines have to make hundreds of thousands of similar pricing decisions daily in their markets.
