Six of the ten busiest international routes in December 2021 operated to or from Dubai, including Dubai-Riyadh which recorded 284,552 seats.

London Heathrow also featured in fourth place with its route to New York JFK (222,890 seats) – the only other US destination to make the top ten was Orlando, with its route to Puerto Rico’s capital San Juan (177,962 seats).
Recent OAG data also showed that Dubai International retained its position as the busiest international airport in the world in December, with over one million more seats than London Heathrow. Amsterdam Schiphol, Paris CDG and Istanbul airport rounded out the top five.
