All air passengers arriving from outside the United States will now be required to have a negative COVID-19 test, not more than 3 days old, before they are allowed to board the plane. This applies to all passengers, including US citizens.

Be sure you understand this requirement, and find a place to have it done, before arriving at the airport.

While this may be difficult to do when you have a full schedule, you will need to take the time to do this, so make sure you schedule it in.
