Ha! Sorry, didn't mean to resurrect a dead project. I just searched for an API to the airport codes and ran with it.
I was actually hoping to find just a data dump of them somewhere, but if you can't I suppose no such thing publicly exists.
My personal recommendation is to do what you want to do. If you don't want to maintain it, perhaps add a note about that, but whatever. You've got no obligation.
Please don't feel sorry about it. I'm actually quite happy to see it's still useful for someone today. I'm just not sure what to do with it next. Right now it doesn't cost me anything to run it anyway. Thanks very much for your idea :)
I was in searching of such a data dump before I wrote AirportCode, but like you said, it's not really available. Some websites sell these data for big fees, which I couldn't pay for, so I ended up scraping Wikipedia for the data. And these things change over the time, which makes it rather complicated to maintain.
I'm thinking maybe something like open source data would be helpful to make these kinds of data available to the public, and let the public to update and maintain it so everyone could benefit from it.
