Within the Country, not necessary. Out of the country. They probably need a Doctor's note.🤔
Masks were required. No fax status check within US.
Flights I took on Saturday did not require a test (domestic travel) but you had to wear a mask at the airport and on the plane.
Only some international travel but some if you are vaccinated just need proof
They need PCR COVID-19 test for international flight
Ditto to what Adriana said.
