Airline Club

So we have accumulated quite a few change requests which I don't have time to address (my parents are leaving today, so I should resume game development soon).

Meanwhile, it would be great if you can contribute with adding the airport and save my time doing all the lookup/coding 

Take note that the whole process is pretty technical, if you are a coder (and a github user), you might find that pretty easy to understand, but it could be a bit challenging for non-coder. Anyway, I put the instructions in https://airlineclub.createaforum.com/airport-and-city-suggestion/please-read-before-posting-)/msg1125/#msg1125
