As of October 2020, Cathay Pacific has merged with Dragon Air. The 8 fights per week from WNZ to HKG have been termintated. Hong Kong Express airlines, newly purchased from Cathay Pacific might start to operate from Wenzhou to Hong Kong, but not well into 2021 or later.
With the exception of a daily flight or two to Taiwan, Macao and Hong Kong, few international flights leave Wenzhou. There are some noteworthy exceptions. During travel periods such as long weekends and Golden Week, charters operate to destinations such as Bangkok, Vietnam and Cambodia. These flights are hard to locate and there may be only one or two dates where these flights exist. They come to be as a tour group requests it and then the extra seats are sold to the public.
This is about to change. Since the new domestic terminal opened, the old terminal which became the international terminal, is begging to be used. In the next few weeks. Bali, Bangkok, Cambodia, Japan and Korea. Soon, certainly other destinations will come online, which we can fly to non-stop. The international airport (Terminal 1) has also placed eGates in position which we may be able to use in the future. Note that Chinese airports have unfortunately developed their own rules from everything to luggage content requirements to immigration rules. My eGate pass for Guangzhou will not work outside of that area, which is weird as my visa is from Wenzhou but I can’t use the eGates here.
Within China, Wenzhou serves a massive amount of cities from extreme NE, the West and the extreme SW. I am always surprised by how many new destinations open each year flying out of Wenzhou. No flights serve the nearby cities of Fuzhou and Xiamen, although Xiamen will likely have flights in the future as their airport explodes in terms of international traffic. Travelers from Wenzhou will hopefully get a connection to fly out of it to N. America and Europe. The prices are competitive internationally out of Xiamen.
As of November 2019, here are the destinations that one can fly out of Wenzhou. Taken from Wikipedia but I dummy booked a few of these in a sampling of the flights I looked at and all are current destinations but quite a few don’t have daily service, especially the farther one is away from Wenzhou. Most smaller airports (cities you’ve never heard before) don’t have daily service. Note Covid has changed some of this list.
