Coast Air Service

Coast Air Service represents the source’s “北京海岸航空服务公司” acquisition thread in 困在系统里的酒店，你不知道的携程垄断练成史. The episode says Ctrip / Trip.com Group bought the company in 2002 to gain airline resources, ticketing-agent qualifications, and offline paper-ticket delivery know-how.

The company is used to show that early online travel was still partly offline fulfillment. Before electronic tickets and mature mobile booking, Online Travel Agency platforms needed physical delivery, invoice, ticketing, and qualification infrastructure.
