Available seat miles - American Airlines Group 2012-2023

American Airlines Group gradually grew its available seat miles (ASM) until the coronavirus pandemic. In the fiscal year of 2020, the U.S. airline had a large decrease in capacity due to social distance measures preventing the spread of COVID-19. In the following years, the company's ASM improved and reached over 277 billion in the 2023 fiscal year.
ASMs are calculated by the total number of seats multiplied by the total distance traveled. When describing the airline industry, people consider ASMs as a measure of capacity.
