Looks to me, deep packet inspection is being done (the great China Firewall mechanism) and everything looking like a VPN just gets a "connection closed" on both sides. Restarting the VPN connection brings back the VPN online and a minute later, the connection is gone again.
So, IF you want to do VPN, you will need obfuscating VPN versions.
Not true.. have used both commercially available VPN (Hotspot shield), as well as my own personal VPN connection to both private servers in HK and NY.. all worked fine, except it does get cut off randomly and I have to reconnect.. But definitely not every minute as you claim...
But back to OP's question, it really depends on the routing that day.. I've taken the JFK 5 to 6 roundtrips the past12 months.. had flights fly way up north over the pole and the connection is stable even when it's supposedly over 60N, but sometimes randomly flying over Wisconsin or parts of China, the internet would get cut off for 45 mins... so YMMV.. but generally wifi coverage seems to be over 80% of the flight..
