Data inconsistency

[pgurusinga]

Hey there @aashishvanand ! I looked into the airport data and noticed a few inconsistencies that I thought you might want to know about:

1. I found around 5 entries that don't have the country code in the 2-digit ISO format. Don't worry though, you can easily search for them using regex "country_code"\s*:\s*"[^"]*airport[^"]*" in VS Code.
2. I also noticed that there are 23 entries without a city name.
   
3. Finally, there are 87 entries without a country name assigned. I hope this information helps you out!
   

let me know if you'd update or I might help
