The world’s 20 busiest international airline flight routes

OAG takes a closer look at the Top 20 busiest international routes by frequency in the 12 months to
February 2018.

These are the world’s busiest trunk routes in terms of the volume of flights that operate on them. Unsurprisingly
the biggest of these routes operate in Asia, with 14 of the Top 20 operating to and from destinations in Asia.
Two operate within Europe, another two operate within North America, and one between North America and
Europe. There is also one route which operates between two destinations in the Middle East.

Using key reports and power tables from OAG Analyser we take a deeper look at these busiest routes, their
profiles in terms of size, carriers which operate them, whether they are growing, to what extent they operate on
time and what aircraft typically operate on the route. We also take a look at how passengers use these routes
to connect onwards to and from other places.
