One thing that would be interesting is scanning for open ports. Once you find an open port, make a Twilio API and text the number (Since most airlines enable texting via SMS/Whats APP) that triggers opening the port on your VPS that is opened on the airplane. Once you do that, you can tunnel into your VPS through the airlines open port or SSH into the machine. If you create a SOCKS5 proxy, then all traffic in your browser will tunnel through the VPS. Haven't tried this, but just a thought.

Back in 2019 when Indian government put a city of 8 million into a 9 month curfew including internet blackout, I was anxious yo get online. Then they permitted only dozen of "white listed websites", just ones that did not allow anti India propaganda. Anyways, I found amazon India worked. I went to aws, set up a vps and simply used ssh tunnel to it. It worked, for a bit. They closed the default port and I could not spend time on a dedicated public internet terminals to " test" open ports so yeah, I have done exactly that. Used foxyproxy btw

  >Used foxyproxy btw HAProxy is also really useful for this purpose, I dare say more-so. For my use-case it solved this problem: "Using 1 port on the remote server (port 443), how can I serve HTTPS (serve a website) and SSH or SOCKS5 (use the server as a proxy)?". HAProxy was good for the task. It could be used to tunnel SSH through HTTPS too, in the case where a corp firewall is using DPI to block standard SSH. What I'm not sure of though... can it tunnel SSH through HTTPS, and, serve a website at the same time? That's a question for the reader. The idea of serving a website at the same time was for the purpose of providing a plausible reason for traffic exists from that server. Like, you know, if the admin's see traffic on 443 from an ip/domain with no website, that's got to be a magnitude of suspicion higher than an ip/domain with an actual website being served on it.

    Sure. If you run an https proxy that allows CONNECT, that can tunnel ssh, but if you do GET without a fully qualified url, that can serve whatever according to the host header. If you just wanted to tunnel ssh over tls, it's trickier because ssh is server speaks first and http is client speaks first, so as a server, you'd have to guess if your client wants one or the other.

It doesn't work like this in the real world. There isn't some magic port that just lets you bypass the firewall. Certain ports sometimes have laxer filtering/restrictions, for example 53, 80, and 443 - but you already know these in advance. You aren't going to find out that port 18741 magically gets you an unrestricted internet connection.
