Need a bigger international airports database

We are currently using your api for our apps. We have an issue where your database is a bit too detailed for our use cases.

We send a push notification every time a user is near an airport to inform their family members of their flight, so they can monitor when the flight lands. The issue arises in big cities that have a lot of helicopter grounds. Could you please inform us how to filter for just the bigger international airports? Maybe you can send a file our devs can use?

Appreciate your help on this one.

It sounds like you just want IATA airports, probably. You could buy our airport database download and filter it to only those airports with IATA codes to get your list. It also distinguishes “special” airport types (heliports, seaplane bases, etc.) if that is useful.
