7 Fly at will

From June, a dozen domestic airline companies, including Hainan Airlines and China Eastern Airlines, launched fly-at-will schemes. Tourists quickly snapped up all the fly-at-will flight tickets. Those who bought China Eastern's "unlimited weekend flights" package for 3,322 yuan redeemed more than 65,000 tickets from June 27 to 28, and nearly 90,000 trips were made using the promotion from July 4 to 5.
