American Airlines consolidates itself as the largest airline in the world in terms of flights and number of seats offered

In 2025, American Airlines consolidated its position as the largest airline in the world in different operational indicators. The data shows leadership both in capacity offered and in the volume of flights carried out throughout the year. According to consultancy OAG, in the ranking of airlines by number of seats offered, American Airlines appears in first place, with 279.6 million seats. Next come the other members of the so-called North American “big four”: Delta Air Lines, with 246.9 million, Southwest Airlines, with 229.2 million, and United Airlines, with 225.5 million seats. The European Ryanair completes the top 5, with 213.1 million, being the only one outside the United States among the five largest in this criterion. American Airlines’ leadership is also confirmed when the ranking considers frequency, which means the total number of flights operated throughout the year. The company carried out approximately 2.3 million flights in 2025, maintaining a significant advantage over its competitors. Delta appears in second place, with 1.8 million flights, followed by United, with 1.7 million, Southwest, with 1.4 million, and again by Ryanair, with 1.1 million departures. In the ranking based on ASKs (Available Seats per Kilometer Flown), a metric that combines capacity and distance flown, the leadership changes hands. United Airlines takes first place, with 536.5 billion available seat kilometers, reflecting a more extensive network and greater weight of long-haul operations. American Airlines comes in second place, with 487.9 billion ASKs, followed closely by Delta, with 483.7 billion. Completing the top 5 are Emirates, with 380.6 billion, and Southwest, with 290.8 billion ASKs. – https://aeroin.net/american-airlines-se-consolida-como-maior-companhia-aerea-do-mundo-em-voos-e-numero-de-assentos-ofertados/
