LONDON -- Disruptions now affect four out of 10 flights in China as punctuality deteriorates sharply, new research shows.
Since June 2017, China's on-time performance -- the ratio of flights that leave the gate less than 15 minutes after the scheduled departure time -- has fallen below 60%. The sheer number of delays is not the only reason fed-up flyers are increasingly switching to the country's well-developed high-speed rail network. In August, the average delay was longer than at any time in the past four years.
