Have you ever wondered what the world’s busiest airline routes are? OAG recently published this data for 2025, and I always find these lists to be quite interesting. Some people know exactly which route will be number one on the list, while others are shocked…
It’s noteworthy (but perhaps not surprising) how the 10 busiest routes are all domestic. It’s also interesting how no route within the United States ranks anywhere close to being among the busiest in the world.
Do any of the busiest airline routes surprise you?
A great solo travel tip spotted this week on One Mile at a Time.
