Outlook for 2025 and Key Challenges
IATA’s Director General, Willie Walsh, highlighted that the strong demand in 2024 demonstrates people’s desire to travel and the efficiency of airlines. However, he warned that in 2025, growth could moderate to 8%, aligning with historical averages. Additionally, Walsh emphasized two critical challenges:
Air Safety: The industry must remain focused on improving safety following recent incidents.
Sustainability: Despite record investments in Sustainable Aviation Fuel (SAF) in 2024, only 0.5% of the fuel used came from these sources. Greater investment and government support are required to increase SAF production and reduce costs.
