Does Macau International Airport still operate under typhoon?

Yes. According to the requirement of International Civil Aviation Organization, an airport should, in addition to serving flights operating to it, also serve as an alternate airport for other flights not commercially destined to it. Therefore, even in the case of bad weather or when a typhoon is hoisted, whether it be a signal number 3, 8, 9 or 10, Macau International Airport will not close but operate 24 hours as usual. However, passengers should understand that flights might be affected or delayed due to unstable weather conditions.
