Pardon my poor Cantonese but like an old ZGGG ATC friend once opined : " chun hai keh sei gweilos "
Assumptions, disinformation and downright hateful nonsense. Are you guys for real? There were massive thunderstorms over most parts of Central and South East China of late. They had severe flooding and storms all over the other airports around ZBAA. Most of their airspace were clogged up with planes deviating and also many planes diverting through their already congested airways.
Even if the wx at ZBAA looked fine, there were many planes diverting to ZBAA and ZBTJ from the other airports. Also there were backlogs of flights delayed from the wx affected airports all making their way to ZBAA once the storms cleared and the Chinese ATC seemed to have given these flights priority. As such other flights had to suffer " ATC hold " due weather.
Same thing happen in the US or anywhere else. When bad weather happens over Philly or KBOS, we had to wait for 2 over hours in JFK because ATC gave priority to diverting aircrafts eventhough JFK wx was fine!
