Dubai International Airport handled 89.1 million passengers in 2018, missing its target but remaining the world's busiest for international travellers.

Dubai Airports CEO Paul Griffiths had told Reuters in February 2018 that double-digit passenger growth could resume as early as this year, aided by closer ties between Emirates and flydubai.
Ambitions To Become The World's Busiest Airport
Dubai Airport has been the world's busiest for international travellers since 2014 when it took the title from London's Heathrow, where passenger traffic grew 2.7% to a total of 80 million passengers in 2018.
In December, Dubai Airport passenger traffic fell by 1.7% to 7.7 million passengers.
Dubai Airport has previously said it believes it can overtake Atlantic and Beijing airports to become the world's busiest overall by 2021.
Hartsfield-Jackson Atlanta International Airport, the world's busiest, handled 98.6 million passengers in the first 11 months of 2018. It has yet to release annual figures.
