IATA: Global Air Travel Hits Record High 4.9 Billion Passengers in 2025

Global air travel reached a new milestone in 2025, with airlines carrying a record 4.9 billion passengers, as international demand, premium travel and airline capacity continued to expand despite persistent geopolitical tensions and supply chain constraints.

The latest World Air Transport Statistics (WATS) released by the International Air Transport Association (IATA) showed that the industry maintained strong growth last year, driven by resilient consumer demand, expanding international connectivity and continued fleet renewal.

The annual report provides the most comprehensive snapshot of global airline operations, covering passenger traffic, cargo, fleet, financial performance and route trends through 2025.

retained its position as the world’s largest air passenger market, handling 890.1 million passengers during the year, followed by China with 776.1 million and the United Kingdom with 269.7 million passengers. Japan recorded the fastest growth among the ten largest passenger markets, with traffic rising 9.2 per cent year-on-year.

One of the strongest trends highlighted in the report was the continued recovery of premium travel.

International business and first-class passenger traffic increased 4.5 per cent to 109.7 million travellers, accounting for 5.5 per cent of all international passengers. Latin America and the Caribbean recorded the fastest growth in premium travel, while Europe remained the world’s largest premium travel market.

The report also underscored aviation’s growing importance to the global economy, with airlines continuing to expand networks, add newer fuel-efficient aircraft and restore international routes suspended during the pandemic years.

IATA Director General Willie Walsh said the latest statistics demonstrate the industry’s continued resilience and its critical role in supporting global trade, tourism and economic growth.

“The 2025 WATS data confirms that people continue to place high value on air connectivity,” Walsh said, noting that airlines are responding with investments in capacity, operational efficiency and customer experience.

The report identified the world’s busiest international airport connections and city-pair routes, reflecting the continued dominance of major global aviation hubs in North America, Europe and Asia.

Within Africa, the Cape Town-Johannesburg route remained the continent’s busiest, carrying approximately 3.4 million passengers during the year, highlighting the importance of domestic aviation in South Africa’s transport network.

IATA also reported continued improvements in airline fleet modernisation as carriers increasingly deployed newer-generation aircraft to improve fuel efficiency and reduce operating costs amid rising sustainability commitments.

The association noted that demand growth continued to outpace several operational constraints, including aircraft delivery delays and supply chain bottlenecks affecting maintenance and manufacturing.

Despite these challenges, airlines maintained network expansion across most regions, with international markets remaining the principal driver of industry growth.

The latest figures come as airlines worldwide continue to balance strong passenger demand with rising operating costs, sustainability targets and geopolitical uncertainties affecting parts of Europe, the Middle East and Asia.

Industry analysts said the WATS report points to a sector that has largely completed its post-pandemic recovery and entered a new phase characterised by capacity expansion, premium travel growth and increasing investment in more efficient aircraft.

For African carriers, the report also highlights the continent’s opportunity to capture a larger share of global passenger traffic through improved connectivity, airport infrastructure and implementation of the Single African Air Transport Market (SAATM), which aims to liberalise intra-African air services and stimulate aviation-led economic growth.
