What happens if my connecting flight is delayed past the 3-day limit for the COVID-19?

If the connecting flight in your trip is delayed past the 3-day limit of testing due to a situation outside of your control (e.g., delays because of severe weather or aircraft mechanical problem), and that delay is less than 48 hours past the 3-day limit for testing, you do not need to be retested. If the delay is more than 48 hours past the 3-day limit, then you will need to be retested.
