Passengers travelling to or connecting through Hong Kong should keep an eye on weather reports and check alternative options with their airlines as Typhoon Kai-tak takes aim for the South China Sea coastline.
The Hong Kong Observatory (HK's weather bureau) has issued Standby Signal 1 warning of a nearby cyclone.
Typhoon Kai-tak (ironically enough, Kai Tak is the name of the old Hong Kong airport too) is currently forecasted to make landfall in western Guangdong rather than Hong Kong, but high winds and stormy conditions may still mean the airport is affected on Friday.
Even if the airport doesn't close, flights are likely to take slightly longer as they skirt around the storm to avoid the worst turbulence. So if your connection is particularly short you might want to double check your options there.
You can expect to see the seatbelt sign on for longer than usual too -- and make sure you bring raingear.
Cathay Pacific is warning passengers of potential disruption at its main hub: "based on the latest weather forecast for Hong Kong International Airport, we plan to operate our flights as scheduled today (16 August). However flights may be subject to disruption between midnight tonight and Friday midday (17 August)".
Up-to-date tropical weather information can be found on the Hong Kong Observatory's website.
And don't forget our standard advice for how to prepare before you leave home if you know you might be running into some trouble.
