Well, will be able to give a better report about the city later today, but the airport seem to be doing fine.
Apart from the new premium terminal (all biz en F pax are asked onboard to make their way there) all Asian Games participants and entourage are asked to stay onboard. They are then transported to the dedicated Asian Games Terminal. This, purpose built, termporary facility is slightly further away and will cope with the bulk of the arriving athleets.
On my overnighter from HKG I had the HKG team, the Taiwan team and some PRC officials, if there were participants from Macau onboarrd then it was a greater China event in the true olympic sense of the word!
