Record load factors and supply-chain strains shaped global air travel in 2025

Full-year 2025 passenger traffic measured in RPK (revenue passenger kilometres) rose 5.3% versus 2024 while available seat kilometres (ASK) increased 5.2%, producing a record annual load factor of 83.6% and underscoring persistent capacity constraints across the industry.

Global performance at a glance

Across the year airlines returned to historical growth paths after the post-COVID rebound: international demand climbed 7.1% and domestic demand grew 2.4%. December closed strong too, with demand up 5.6%, capacity up 5.9% and a December load factor of 83.7%. These figures reflect robust traveller appetite but also reveal operational stresses that directly affect the travel experience.

Operational pressures: supply chain and decarbonization

Two structural issues dominated airline operations in 2025. First, decarbonization: expanding Sustainable Aviation Fuel (SAF) production and supportive fiscal frameworks remain essential if aviation-driven connectivity and tourism growth are to be sustained long term. Second, supply-chain bottlenecks—delayed deliveries of new aircraft and engines, constrained maintenance capacity and higher costs—forced carriers to keep older aircraft in service and push load factors upward. Industry estimates place related cost increases at more than $11 billion for 2025.

How this affects travellers and tourism

• Higher load factors mean fewer empty seats and less downward pricing pressure on popular routes.
• Delivery and maintenance shortfalls can translate to irregular schedules or limited frequency on leisure routes, affecting tour planning.
• Faster SAF rollout and newer aircraft fleets would improve comfort, noise, and emissions profiles—beneficial for sustainable tourism markets.

Regional highlights

Notable regional trends

• Asia-Pacific led growth with a 7.8% annual rise in RPK and the highest load factors—critical for outbound tourism flows across the region.
• Europe and Latin America also saw strong international demand, but Latin America expanded capacity faster than demand, trimming load factors slightly.
• North America recorded the slowest growth; the domestic US market showed modest contraction in passengers compared with other domestic markets.

Domestic markets and country-level signals

Domestic travel hit record passenger numbers and load factors in aggregate, though performance varied by country. Brazil led domestic RPK growth (+11.1% year-on-year for 2025). India maintained the highest domestic PLF among large markets (about 85.2%), while the United States registered a small contraction in passenger traffic and a notable fall in load factor.

Practical advice for travellers and tour operators

• Book early and consider flexible fares—higher load factors limit last-minute availability.
• Allow extra connection time; maintenance-related irregularities can cause schedule changes.
• When planning sustainable or premium travel, check whether operators use newer aircraft or SAF-compatible services.

At a glance, 2025 combined strong passenger demand with real operational strain. The industry needs accelerated aircraft deliveries and expanded maintenance capacity to convert this demand into improved choice and reliability. Willie Walsh highlighted that every new aircraft increases capacity and reduces noise and emissions—outcomes that matter for travellers and destination communities alike.

In summary, 2025 delivered growth in global air travel measured by RPK and a record PLF, yet capacity constraints and supply-chain pressures limited airline options. Key takeaways: prioritize early bookings, expect variable regional dynamics, and look for operators emphasizing newer, cleaner aircraft. Travelers and industry players should monitor SAF rollout and fleet renewals as indicators of improved service.
