SPASPA: full name of SpecialProrateAgreement, which is allocated according to special account split or proportion. SPA refers to the sales agreement between two airlines, which mainly stipulates the price, booking space and related restrictions (such as whether the third airline is allowed to connect, the sales validity period, whether there is a sub-price, etc.). ) When the ticket book of China Eastern Airlines opened an airline segment. For example, if a guest wants to fly PVG- Mu -BKK-cx-SIN on a ticket of China Eastern Airlines, China Eastern Airlines itself will not fly BKK. But he also signed Cathay Pacific's SPA agreement, a paragraph of 100 dollars, leaving the cabin for M, that is, MU's sales. As long as he decides the sales price of China Eastern Airlines PVG-BKK+65,438+000, he can get the market sales price. For a regional airline, it is very important to sign more or less spa with other airlines, which can help these airlines overcome the problem of insufficient network coverage, whether good or bad. Dragonair has many good spas in this respect, which increases the usage of KA. However, you need to be very careful when using SPA. It doesn't matter if the price is wrong, but you need to be very careful when booking space or restricting flights, otherwise the carrier airline will announce the freight rate on the computer of the flight segment. (SPA is generally confidential)
