The civil aviation authority is considering measures to punish people who behave badly on airliners, said a senior official.

Li Jiaxiang, director of the Civil Aviation Administration of China, said the agency plans to include unruly passengers on a "personal negative credit list", which will affect their future air travel. He did not elaborate on to what extent these passengers will be affected.

"Everyone must behave well while traveling," he said on the sidelines of the agency's annual work conference in Beijing on Thursday. "Despite the recent scandal being caused by only a few passengers, it has strongly tarnished the image of Chinese travelers."
