Hello
We’re putting toegther a Team of Developers to make high quality Airports. As we cant decide which Airport we first wanna approach, we want to ask the community and find out what the most requested Airports are. We are not interested in doing some small town Airports, so please leave them out!
For me personally it is KBOS 
@CptRaid,
I think this is the thread you may be looking for, for the information you are asking:

If I have made a mistake, or have closed this thread in error, then please send a PM to @moderators and we can take a look at maybe opening this thread again.
Regards
