From 3 November 2026 at 23:59 US Eastern time, all passengers, including US citizens, must submit a declaration before boarding that they have not been in the Democratic Republic of Congo during the previous 21 days.
The measure was introduced by the US Centers for Disease Control and Prevention (CDC) and applies to passengers flying to the US on international flights.
Those who have been in the DRC in the past 21 days will not be boarded. Air Serbia advises completing the declaration in advance to avoid delays at boarding.
