Airline staff are required to make sure that passengers have all the required authorizations for the destination they're headed to. So now, when you're leaving the United States, you have to present proof of your negative test results and travel authorization in person. That means, in most cases, you can no longer check-in online, so allow yourself extra time at the airport.
