Do they require covid test for arriving or departing the airport?

Not if you’re coming from the USA…. If you are flying out of the country, yes, you need a PCR test.

Not for the airport, just for getting on the international flights

International flights only

Sascha Reyes, no Covid-19 for domestic flights. American Airlines didn't asked me it

Hi, I flew domestic and was not required to provide COVID testing or results. But it's a good idea to have the information just in case.
