Star alliance, founded in 1997, is based in frankfurt, germany, and is the world's airline union. The five members of the alliance's english-language name and logo representatives were formed: nordic airlines, thai airways international, air canada, lufthansa and united airlines. Alliance of aviation, which integrates the network of routes, vip waiting rooms, on-line services and ticketing services. The tourist experience can be enhanced wherever the customer is in the world. Co-coordination and arrangements among the members of the alliance will provide more passenger flight options, more ideal flight transfer times, simpler ticketing procedures and better ground handling services. Eligible passengers will have access to more than 990 airport vip rooms worldwide and mutual privileges and courtesy. In addition to being on any flight of any member of the alliance, the cumulative mileage may be converted to the account of the rti of any member aviation, thus becoming a distinguished member of the scheme. Members of the group are entitled to reservation and post-air terminal spot confirmation, priority being given to airport reporting, boarding, customs clearance and baggage shipment procedures. In addition, the passengers of any sau are provided with full and unrestricted air tickets and, if a temporary change is made at the airport, they can change their flights directly to other members of the alliance without the need for a letter of endorsement from the original air carrier. In addition, the sau has designed the "symmetric ufo" ticket, which is based on the number of fly miles, which is cost-effective, plus the union's intensive network of routes, to provide an easy travel route. The main forms of cooperation of the alliance include the expansion of code-sharing, the sharing of points in the frequent flyer program, the coordination of the serial and flight schedules of the line distribution network, the sharing of service counters at various airports with vips, and joint implementation of image promotion activities. As opposed to the complex form of cooperation among airlines, the use of the services of the alliance is relatively simple for passengers on board, and only any of the individual regular passenger programmes offered by member airlines (which do not add up to duplicate the ffp of different companies) is required to accumulate the mileage of the different airline flights in the same ffp. In addition to this, the trans-corporate long-distance leg was considered to be a link to the internal routes of the same company, thus providing more opportunities for preferential fares. The sau preferences include: the regular passenger scheme; the sau gold/since card level; the vip lounge; the acquisition of mileage/centres; the sau awards; the sau upgrading awards; the switchboard; and the same roof scheme (member airlines operating in the same terminal). Isau products and services also include ticket packages and airline tickets. The establishment of a common ticket counter at frankfurt airport, germany, the establishment of the alliance's municipal ticket centre in london, the exclusive asau vip room at hong kong international airport and members to the extent possible, in the same terminal building at the airport are indicative of the efforts of the alliance to provide more facilities for passengers to purchase tickets, report to and board the airport, while reducing costs and increasing efficiency in lieu of competition。
