Air tickets are usually only available at the departure location (for example, special-priced tickets from Beijing to Xi'an can only be purchased in Beijing), because most of the special ticket sales policies are set by the local market personnel of the airline, and they do not notify ticket sales agents in other places. In the civil aviation sales computer system, special-priced tickets have a special discount level instead, which the sales agents in other places cannot understand or sell without authorization. Therefore, the possibility of purchasing special-priced tickets for another place's departure is very small. For instance, it's almost impossible to buy special-priced tickets from Beijing to Xi'an while being in Xi'an. Now many airline ticket offices advertise with "a phone call to travel across China", which refers to national chain services (but many such companies actually don't have that capability, unable to set up ticket offices in all cities, so they cooperate with local ticket companies to share profits. The local ticket companies think these aren't their direct customers, and still need to share part of the profit, leading to rigid attitudes towards customers, untimely ticket delivery, and even charging customers for ticket delivery fees). They establish call centers, providing unified services for passengers nationwide, meaning wherever you are, as long as you call this number, they can purchase tickets for you and deliver them to your hands. But can you buy special-priced tickets? In March 2006, for the Xi'an to Beijing flight, the selling price was 90% (950 yuan), while in the Xi'an market, there were 40% special-priced tickets (420 yuan) available, which is impossible to know and buy elsewhere. Can those so-called unified call center customer service representatives know this? The answer is definitely no. There are so many domestic and international flights, and the sales policies of airlines change daily, differing by proximity. Even local sales agents may not necessarily get all the policies, how can sales agents from other places master them? Therefore, I suggest if you want to buy special-priced tickets, you should inquire and purchase from local ticket sales enterprises at the departure station.
