IATA tracks the trends in the 2025 edition of World Air Transport Statistics

In 2025, the number of international premium-class passengers — business and first class — reached 109.7 million, up 4.5% year-on-year; and accounting for 5.5% of all international travellers, according to the latest edition of IATA’s World Air Transport Statistics (WATS) that provides comprehensive statistical data through to 2025.

In that same year, Latin America saw the largest jump in premium-class passengers, rising 22.1% to 4.0 million. Europe remained the biggest market for premium travel, with 39.7 million passengers in 2025.

However, North America (10.4%) and the Middle East (9.5%) accounted for the highest shares of premium-class passengers as a proportion of total passenger numbers.

Asia Pacific dominated the ranking of the world’s busiest airport pairs, with Jeju International Airport-Seoul’s Gimpo International Airport (CJU-GMP) remaining the most popular route globally, with 13.3 million passengers traveling between the two airports.

In the top 10, only one airport pair — Jeddah’s King Abdulaziz International Airport-Riyadh’s King Khalid International Airport (JED-RUH) — was outside the Asia Pacific region. All of the top 10 busiest airport pairs were domestic connections.

An overview of the regions found that:

• Cape Town International Airport-Johannesburg’s OR Tambo International Airport (CPT-JNB) was Africa’s busiest airport pair in 2025, with 3.4 million passengers.
