Three detained in air travel incidents

Chinese police have detained a man in an attack on an airline check-in clerk that left her lying in a pool of blood and arrested two others who charged the cockpit as their flight was taxiing for takeoff.

They were the latest in a growing tally of dangerous acts involving Chinese airline travelers.

A statement from the Civil Aviation Administration of China said two men aboard a Hainan Airlines flight from Datong, Shanxi province, to Chongqing municipality on Sunday demanded to be upgraded to business class as their flight was taxiing.
