Delays in new aircraft deliveries restrict growth in air transport industry
The International Air Transport Association (IATA) updated its analysis of aerospace supply chain bottlenecks noting that aircraft availability remains one of the most significant constraints on industry growth in its just released global outlook.
While deliveries of new aircraft began to pick up in late 2025 and production is expected to accelerate in 2026, demand is forecast to outstrip the availability of aircraft and engines. The normalization of the structural mismatch between airline requirements and production capacity is unlikely before 2031-2034 due to irreversible losses on deliveries over the past five years and a record-high order backlog.
Notable points on the current situation include:
• Delivery shortfalls now total at least 5,300 aircraft.
• The order backlog has surpassed 17,000 aircraft, a number equal to almost 60% of the active fleet. Historically, this ratio was steady at around 30-40%. This backlog is equivalent to nearly 12 years of the current production capacity.
• The average fleet age has risen to 15.1 years (12.8 years for aircraft in the passenger fleet, 19.6 years for cargo aircraft, and 14.5 years for the wide-body fleet).
• Aircraft in storage (for all reasons) exceed 5,000 aircraft, one of the highest levels in history despite the severe shortage of new aircraft.
"Airlines are feeling the impact of the aerospace supply chain challenges across their business. Higher leasing costs, reduced scheduling flexibility, delayed sustainability gains, and increased reliance on suboptimal aircraft types are the most obvious challenges. Airlines are missing opportunities to strengthen their top-line, improve their environmental performance, and serve customers. Meanwhile, travelers are seeing higher costs from the resulting tighter demand/supply conditions. No effort should be spared to accelerate solutions before the impact becomes even more acute," said Willie Walsh, IATA's Director General.
