The company is one of the oldest legacy carriers in the United States and was formed by the merger of legacy carriers such as Western Airlines, which was acquired in 1987, or Northwest Airlines, which was acquired in 2008, and others. Headquartered at the busiest airport in the world, the Atlanta-based company transports more than 170 million passengers every year with connections to some 321 destinations in the world.
The airline’s growth in providing passenger air transportation services can be seen in the increasingly operating revenues over the last years. In the fiscal year of 2018, it generated over 44.4 billion U.S. dollars in revenue. In that same period, it had a seat capacity of more than 263 billion available seat miles and a passenger load factor of 85.5 percent.
The airline is often ranked among the best airlines in the world in terms of passenger kilometers, profitability or in-flight connectivity. In 2017, it was the leading airline worldwide providing Wi-Fi on its flights.
