On my flight home yesterday a free, but limited, wifi option was available that allowed only for messaging (WhatsApp, Messenger, and I think the Google and Apple ones were specifically mentioned), but not web browsing. I checked and, sure enough, I couldn't get web browsing to work, but WhatsApp and Messenger worked fine. I decided to try my XMPP client and I was pleasantly surprised to that that worked fine as well.
I know it's a limited use case, where XMPP is one of the few unblocked protocols, but are there things I can do with it besides chatting? Could I use it to receive status updates from my server? Is there a way to use it for SSH somehow? I guess some sort of bot running on my server would be required. Seems like there are lots of possibilities, like bots that fetch websites or interact with ActivityPub. Has anyone found or tried anything like that?

You can do SSH tunneling over DNS, so everything is possible.
Wait how do you do that? Local port forwarding with
ssh -L?You can basically connect any local port to any remote port normal or reversed. Reversed is -R, normal with -L. In this setting, correct me if im worng, you want to connect the open port on the airplane to one already prepared on a vps which allows you to do what you want e.g. proxy websites.
The option
-D $portcreates a SOCKS5 proxy which can be used by most browsers, and will auto tunnel everything.
