1-2-3-4: No, no, no, no. For internal travel within the USA, nobody cares, nobody checks, nada. TSA is concerned with water bottle confiscation and narco traffickers. They don’t look twice at your itinerary. The only COVID questions will be at customs immigration and that’s only upon entry to USA to ferret out sick people.
California doesn’t care where you have been just wear a mask in public and be smart. NYC has lot of rules but zero enforcement. This is the state that sent sick people back home to reinfect others and die. Not a model of success.
