Global air passenger traffic reached a record level in 2025 as airlines carried more than five billion passengers, according to the International Air Transport Association (IATA), underscoring aviation’s growing role in tourism, international trade and business travel.
The figures were contained in IATA’s 2025 World Air Transport Statistics (WATS) released last week. The annual report provides a comprehensive overview of global airline performance, passenger demand, cargo operations, fleet development, employment and financial performance across the aviation industry.
According to IATA, airlines operated more than 40 million scheduled flights during the year, reflecting demand for both domestic and international travel across major airlines.The report also showed that premium-class travel maintained strong momentum, with business and first-class passenger numbers rising 4.5 per cent year-on-year to 109.7 million, representing 5.5 per cent of all international travellers.
The report identified the United States as the world’s largest passenger market in 2025 with 890.1 million passengers, followed by China with 776.1 million passengers. Several airlines also recorded notable growth, including Kazakhstan, where passenger traffic increased by 40 per cent, while Vietnam posted a 14.8 per cent rise.
Air cargo also posted solid performance, supported by expanding e-commerce, international trade and global supply chain activities despite economic uncertainties in several regions. IATA said the figures reflect aviation’s expanding contribution to global commerce and economic activity.
The report further showed that the Boeing 737 remained the world’s most widely used aircraft, operating 10.8 million flights in 2025, ahead of the Airbus A320, which recorded 8.7 million flights, highlighting airlines’ preference for fuel-efficient narrow-body aircraft as passenger demand rises.
IATA also noted that the aviation sector continues to support tourism growth by improving connectivity between destinations, encouraging business travel and facilitating international visitor movements. The report highlighted Asia-Pacific as home to the world’s busiest airport pairs, while Africa’s busiest domestic route remained Cape Town–Johannesburg, which handled 3.4 million passengers during the year.
The latest figures reinforce the importance of sustained investment in airport infrastructure, airline expansion and tourism development as countries seek to attract more visitors, stimulate business travel and strengthen their position within the global aviation economy.
