72 Hours is 3 Days.
What is considered 3 days? The 3-day period is the 3 days before the flight's departure. The Order uses a 3-day timeframe instead of 72 hours to provide more flexibility to the traveler. By using a 3-day window, test validity does not depend on the time of the flight or the time of day that the test was administered.
