Hainan Airlines has launched limited 90%-off air tickets for its three routes departing from Chongqing, and this has caused dissatisfaction among other airlines.

A representative from one of the airline companies said the discounted air tickets is a clear case of dumping, and they already submitted their complaint to the CAAC Southwest Management Bureau. Also these airline companies are asking their ticket agencies not to sell Hainan Airlines' tickets.

By January 10, all the 90%-off flight tickets offered by Hainan Airlines had been sold out, but since they also launched unlimited 80%-off tickets for the same routes, there is still a long queue each day at their ticket office.

A representative from CAAC Chongqing Office said that there isn't a clear rule to follow in dealing with this situation. He said that both the behaviors of Hainan Airlines and other airline companies are not good, because this will ultimately make passengers suffer.

The headquarters of Hainan Airlines has already sent its representative to Chongqing to negotiate with other airline companies in solving the problem.
