World's busiest air routes for 2024 revealed with Sydney-Melbourne in fifth place

The Sydney-Melbourne route remains the world's fifth busiest in 2024, with 9.2 million available seats. This is a 7% decrease from 2019 and a slight drop from last year, following the collapse of regional airline Rex in July. The busiest route globally is from Seoul to Jeju, with over 14 million seats. Other top international routes include Hong Kong to Taipei and Cairo to Jeddah, reflecting a strong recovery in Asian travel and increased leisure demand. In the domestic rankings, Sydney-Melbourne leads, while the only transatlantic route in the top ten is New York to London, with 4 million seats. The overall trend shows a shift towards leisure travel over business trips post-pandemic.
