Hi @UndueSeven9265!
As @EpicPrimus pointed out, for missing airports first report to zendesk. Then on this topic https://forums.flightsimulator.com/t/missing-airports-sent-to-zendesk/165814 make a new post with the airport code and that it’s been reported to zendesk. It would help too if you know the coordinates of that airport.
Thank you for reporting this!
