United In-Flight Wi-Fi JSON

United In-Flight Wi-Fi JSON

This is a small script I wrote that allows you to parse information of your flight when connected to United's In-Flight Wi-Fi. It provides information such as expected/actual departure, arrivals, airports, temperatures, altitude, ground speed, miles accrued for the flight and the flight number.

Install

Copy united.rb to your computer and install the following gems:

$ gem install httparty
$ gem install nokogiri

That's it! Run it by executing ruby united.rb or include it in your own Ruby script. See the file to find out what functions are available or just get a JSON output by executing United.to_json.

Note: You do need to be connected to a United's In-Flight Wi-Fi, but you do not need to pay for the internet for it to work. It'll work regardless if you've paid for internet or not.
