> Obviously, one solution to the problem is that DHCP leases on planes should be drastically shorter, like at 1 hour intervals. Secondly, the number of leases should be drastically increased.

Why isn't the solution as simple as, "Reset the Internet at every flight turnover"? Once the plane lands and (almost) everyone deplanes, hit the button as another step in crew handover.

Between “crew has to remember to hit the button” and “everything just works,” I have a strong preference for the second one.

That would help, but I can imagine that on larger planes, especially if people connect their phone, then later their laptop, and so on, you could hit the limit of a 192.168.x subnet even during a flight.
