how is it an exaggeration? only 15 minutes delay is a fast getaway for A461! It's not just the 'great wall' 4800m restriction though, what the article misses entirely is the massive gulf between ICAO separation standards and Chinese separation standards. It's a lateral choke as well as vertical.
Next time every airport in northern China is closed for the day they could investigate what happens in other countries when it snows (...nothing...)
It's great to see some mass media exposure for the inefficiencies of aviation in our neighbourhood. But as with everything Chinese, it's all constantly improving
