With close to 3.5 million seats, the route between Vancouver International Airport (YVR) and Toronto Pearson International Airport (YYZ) was the busiest domestic airline route in North America in 2024, while a domestic route in the Middle East offered more than 8.7 million seats. But which are the busiest domestic airline routes for February 2025?
The effect of the Leap Year on any comparison with February 2024 should be noted, as does the fact that the number of seats each day in February provides an adjusted direct comparison with the previous year. The Jeju (CJU) – Seoul (GMP) route saw a 14% drop in seats per day in February 2025 compared to the previous year. Let’s look more detail about the busiest airline route for February 2025.
