I assume you’re talking about tunneling TCP over DNS queries. Does that really work on airplanes? A link to the code would be appreciated. I thought captive portals force you to use their DNS servers by grabbing all UDP packets with the DNS port (regardless of destination IP) and those servers respond with the webserver’s IP regardless of what you query.

It does TXT record lookups or equivalent. Those get resolved correctly without any interference from the captive portal. Here is something similar in technical nature to what I have used in the past (free DNS VPN apps on ios) https://github.com/JadenGeller/Burrow-Client https://github.com/JadenGeller/Burrow-Client
