Feng Zhenglin, head of the Civil Aviation Administration of China, said the country's aviation sector will boost efforts to provide higher quality services, as well as improved safety and accessibility.

The on-time rate of national flights reached 80.13 percent, the highest level since 2010. Passengers also saw more quality services at airports with a paperless ticketing drive, a better ticket change and refund system and wi-fi coverage on more than 300 planes, Feng said.

The paperless strategy was used for 225 million passenger trips, allowing improved convenience and saved 18.75 million hours, he added.

These outcomes came as the administration launched a campaign in 2018 to improve service quality and management in the civil aviation industry.

The administration will continue to seek improvement in airport on-time performance, ticket sales, flight wi-fi availability and complaint-procedure handling, he said.

And it will further promote its new security check, which classifies and guides passengers to different security checks based on their past safety credits. It provides a "green" channel for passengers with good credit which can speed up the process and save time, Wang said.

The administration will launch a designated phone service on March 15 to better handle customer complaints, Wang said, adding that if the passengers fail to get a response from airlines or airports, the administration will ensure feedback after receiving their calls, according to Wang.
