World’s Busiest Airlines By Number of Flights

In fact, there are dozens of attributes to rate, rank, and benchmark airlines: Number of passengers, destinations, or capacity are just a few examples. However, the number of flights is one of the attributes that perfectly reflects the current size of an airline. That’s why we specifically looked at this figure and put together the lists of the world’s busiest airlines. Here’s what’s contained in detail:

Top 20 World’s Busiest Airlines

When looking at the world’s busiest airlines, China and the United States continue to dominate the ranking. Twelve of twenty airlines are based in the United States or China. Unsurprisingly, the picture is identical to the latest airport ranking.

Four Airlines With More Than 100,000 Flights
In June 2021, four airlines operated more than 100,000 flights. However, all airlines are located in the United States: American Airlines, Delta Air Lines, United Airlines, and Southwest Airlines. Based on the number of flights, American Airlines is by far the world’s busiest airline — operating almost 45,000 flights more than Delta on rank 2.

European and Latin American Airlines’ Traffic Remains at low Level.
Only five out of the 20 busiest airlines are based in Europe or Latin America. Moreover, the number of flights is relatively low compared to the big US or Chinese players.

Asia – Pacific Top 20 Busiest Airlines

Unsurprisingly, the vast majority of Asia’s busiest airlines are based in China. More precisely, eight of the top 20 are located in China. Moreover, the number of flights varies largely between the top Asian players and airlines ranking on position ten or lower. For example, whereas China Eastern on the first rank operated more than 60,000 flights, Japan Airlines on position ten handled 14,000, and SpiceJet on position 20 operated only 6,000 flights.
