Global demand for air travel continued its steady ascent in 2025, expanding by 5.3% compared to 2024, according to the International Air Transport Association (IATA). The growth, measured in revenue passenger kilometres (RPKs), signaled a return to long-term industry trends following the post-pandemic surge.
Airline capacity, tracked in available seat kilometres (ASKs), grew by 5.2% last year, while passenger load factors edged up to an all-time high of 83.6%, an increase of 0.1 percentage points from 2024.
Middle East Delivers Strong Traffic Growth
Carriers in the Middle East emerged as top performers in 2025, posting a 6.7% jump in traffic over the previous year. Capacity expanded by 5.8%, driving load factors up 0.7 percentage points to 81.6%. December wrapped up strongly, with a 9.5% year-on-year rise in regional demand.
International and Domestic Market Trends
On the international front, passenger demand for 2025 rose by 7.1%, alongside a 6.8% capacity gain. The global international load factor reached a record 83.5%, up slightly from the prior year.
Domestic travel growth remained more modest, with demand up 2.4% and capacity up 2.5%, producing an average load factor of 83.7%, down marginally by 0.1 points.
December concluded on a positive note, as overall traffic grew 5.6%, capacity increased 5.9%, and load factors held steady at 83.7%.
IATA: Focus on Sustainability and Supply Chains
“The 5.3% increase in air travel last year reflects the industry’s return to pre-pandemic growth norms,” IATA stated. “As we move forward, two key issues—decarbonization and supply chain stability—will define aviation’s ability to meet future demand.”
IATA emphasized that achieving climate goals requires clear policy support from governments to expand Sustainable Aviation Fuel (SAF) production and ensure energy sector collaboration.
Persistent supply chain disruptions were another hurdle for airlines in 2025, creating what IATA called "the industry's biggest frustration of the year.” Aircraft and engine delivery delays, maintenance backlogs, and related cost pressures—estimated at over $11 billion—forced airlines to extend fleet usage and increase seat occupancy.
“With aircraft nearly 84% full, these temporary fixes were effective but not sustainable,” said Willie Walsh, IATA’s Director General. “The industry needs lasting solutions. Ideally, 2025 marks the low point of the supply chain crisis, paving the way for recovery in 2026. Every new plane in service represents cleaner operations and greater capacity for passengers.”
Regional Highlights
Asia-Pacific airlines led global growth, reporting a 10.9% increase in international RPKs and a 10.2% rise in capacity. Their load factor climbed to 84.4%, the highest of any region.
Europe saw international demand increase 6.0%, with capacity up 5.9% and load factors holding at 84.1%.
North American carriers reported more modest figures, with traffic up 2.1% and capacity up 2.4%—the slowest growth among all regions. Load factors dipped slightly to 83.9%.
Latin American airlines recorded an 8.6% rise in annual traffic, but capacity growth outpaced demand at 10.2%, pulling load factors down 1.2 points to 83.6%.
African carriers achieved a 7.8% annual traffic increase with capacity up 6.5%, pushing load factors to a record 74.9%, the largest improvement among all regions despite being the lowest overall.
Domestic Market Performance
Domestic air travel also reached record highs in 2025, though growth moderated after the previous year’s rebound. Brazil topped the charts with an 11.1% rise in passenger traffic, while the United States experienced a 0.6% decline.
Japan posted the strongest improvement in load factor (+3.4 percentage points), in contrast to the U.S., where the load factor dropped by 1.9 points. India maintained the world’s highest domestic load factor at 85.2%, even with a small decrease. Australia recorded the lowest at a still-solid 81.2%.
