Good luck with your son's flight. He should wear a mask as soon as he starts stepping in the area where other people are standing or walking & especially when he goes for security clearance and after that of course we must keep using the mask during his flight. 6 feet social distance will also be required for sure.
only restrictions are that masks are still required at all times
Information about airline policies regarding CoVid should be available on the airlines website
Not that I know of but everyone is required to still wear the mask on the plane for the whole duration of the flight
Just have to wear a mask on flight and in all airports
