PySkyWiFi: completely free, unbelievably stupid wi-fi on long-haul flights

PySkyWiFi is a tool that exploits a loophole in airline airmiles accounts to access the internet on flights without paying. By using Python and implementing a simplified TCP/IP protocol, the author created a sky proxy on their laptop and a ground daemon on an internet-connected computer. This setup allows full HTTP requests to be sent via the airmiles account, albeit very slowly. The post includes detailed instructions on how the system works, as well as highlights the potential fun and productivity achieved during a long-haul flight.
