Taipei/Beijing, Sept. 22 (CNA) China's Spring Airlines said Monday that Taiwanese passengers can use their Taiwan Compatriot Permit and Republic of China (Taiwan) passport to book international flights, following the resolution of a system issue that temporarily blocked such bookings. Speaking to the media in Taipei, Ding said the issue arose during a recent system upgrade, when some routes showed incorrect documentation options online, and there were also miscommunications between passengers and customer service. After contacting Spring Airlines' customer service staff in China later in the day, a CNA reporter was told that Taiwanese purchasing tickets to go abroad, such as Japan, are required to use their ROC passport. Taiwanese nationals can book tickets directly and normally without any restrictions, the customer service responded.
