Orlando International Airport is still the busiest airport in Florida, and it just climbed higher in the national rankings. Airports Council International North America (ACI-NA) released its 2025 airport traffic rankings, and Orlando International Airport (MCO) moved from 9th place in 2024 up to 7th place in 2025.
MCO also ranks as the 25th busiest airport in the world.
Passenger Numbers at MCO
Passenger traffic at MCO grew slightly in 2025, reaching 57,675,573 travelers. That's up from 57,211,628 in 2024. Some of that growth came from new international routes. Orlando added three new nonstop flights across the Atlantic this year, to Munich, Madrid, and Paris.
Nationally, passenger traffic dropped 0.7 percent in 2025 compared to 2024. Domestic passenger volumes fell 1.0 percent, while international travel grew 0.3 percent. MCO went the other direction, posting a 0.8 percent increase in total passengers.
GOAA CEO Lance Lyttle pointed to Central Florida's continued growth and appeal as reasons behind the numbers, adding that a strategic vision for the airport will guide customer service and infrastructure improvements in the years ahead.
