I think this is an okay place to ask this. Let me know if it is not.

In about a month, my school is going on a school trip and the plane ride is going to be around 15 hours. I was think about setting up a small network on the plane so that we can chat on a locally hosted program.

I would do this by bringing a small router and hooking it up.

Is this against the rules of most airlines and do you think I could get in trouble?

    $\begingroup$ I'm guessing you are considering a wireless router, because even if you are sitting together, Ethernet cords everywhere have their own issues. $\endgroup$ – fooot Feb 7 '15 at 18:42

    $\begingroup$ You need to check with the airline. Some airplanes (especially international) have in-inflight wifi, so you should be fine using that. If it doesn't have in-flight wifi, it might not be rated for wifi, in which case the answer is probably no. $\endgroup$ – raptortech97 Feb 7 '15 at 18:50

    $\begingroup$ @raptortech97 I'm hoping that if they do have in-flight WiFi, it doesn't allow you to directly connect with other devices on that network. $\endgroup$ – fooot Feb 7 '15 at 19:26
  • $\begingroup$ @fooot yeah I don't know how router security works at all. But isn't there some way it could work? With like.. a VPN I think?? $\endgroup$ – raptortech97 Feb 7 '15 at 19:27
  • $\begingroup$ @raptortech97 software developer here, it is possible (and probable) that the in-flight WiFi does not allow client-to-client connection. In that case you'll need to turn the WiFi connector of your laptop into a router, which isn't that hard really (lookup "netsh wlan start hostednetwork"). $\endgroup$ – kevin Feb 7 '15 at 19:35
