The 20 biggest airlines in the world, ranked


Over the past century, the airline industry has changed the way humans travel. It has effectively made the world a smaller place – making it possible for billions of people everywhere to explore the world.

According to the International Air Transport Association (IATA), consumers spent an estimated $US871 billion, or roughly 1% of the global GDP, on air travel.

The trade group, which has a membership made up of 290 airlines, expects the total number of airline passengers around the world to reach 8.2 billion people by 2037 – that’s double today’s passenger count.

As a result of the industry’s growth, many of the world’s airlines have become household names. Through recent mergers, American, Delta, United, and Southwest have grown to become colossal mega-carriers.

This got us at Business Insider thinking about how they stack up against the largest airlines.

Fortunately, the good folks at OAG provided us the data sets that answered our question.

The London-based aviation-data-and-intelligence firm ranked the world’s airlines based on the total number of seats each carrier made available to customers during 2018. OAG also included the total number of aircraft in each airline fleet.

Some airlines on the list offer substantially more seats while operating fewer aircraft.

According to OAG senior analyst John Grant, this variation is because of the differences in the planes that comprise a carrier’s fleet and the seat configurations of each aircraft. As a result, airlines that operate larger aircraft and aircraft with higher seat density will be able to make more seats available to customers.
