Airlines globally achieved record seat occupancy in 2024, with an 83.5% load factor for full-year traffic, reflecting the percentage of available seats filled with paying passengers and demonstrating how efficiently airlines utilized their capacity.
The impressive load factor statistics in 2024, coupled with a 10.4% increase in air passenger demand, highlighted that people were eager to travel last year.
This data is sourced from the full-year and December 2024 passenger market performance report recently released by the International Air Transport Association (IATA).
Willie Walsh, IATA’s Director General, attributed the new record-high load factor airlines achieved in 2024 partially to the supply chain constraints that limited capacity growth, forcing airlines to optimize the available seating.
“2024 made it absolutely clear that people want to travel. With 10.4% demand growth, travel reached record numbers domestically and internationally. Airlines met that strong demand with record efficiency. On average, 83.5% of all seats on offer were filled—a new record high, partially attributable to the supply chain constraints that limited capacity growth,” the report quoted Walsh saying.
The report further highlighted that, alongside the full-year load factor and passenger demand growth data, global airlines’ capacity increased by 8.7% in 2024. Airline capacity, which refers to the total number of seats available for passengers, played a crucial role in this growth.
IATA also reported a 13.6% increase in international full-year traffic compared to 2023, with capacity rising by 12.8%. Domestic traffic grew by 5.7%, while capacity expanded by 2.5%.
December 2024 marked a strong finish to the year, with overall demand rising by 8.6% year-on-year and capacity increasing by 5.6%. International demand grew by 10.6%, while domestic demand rose by 5.5%. The December load factor reached a record 84%.
For December, international demand increased by 10.6%, capacity grew by 7.7%, and the load factor improved by 2.2 percentage points to 83.9%, compared to December 2023.
The IATA report also provided a regional breakdown of airline performance for both the full year and December 2024.
Looking ahead to 2025, IATA expects demand to continue its upward trajectory, albeit at a more moderate pace of 8.0%, in line with historical averages. However, the industry will face challenges, including the need for ongoing safety improvements and heightened investment in Sustainable Aviation Fuel (SAF) to meet long-term sustainability goals.
