ACI Warns Global Airports Are Reaching Capacity Limits.
Surging passenger traffic strains airport infrastructure worldwide.
Airports Council International (ACI) reported that global passenger traffic surged throughout 2025, pushing many major airports close to operational capacity. Congestion and delays became more frequent at major hubs.
FlightGlobal and AeroTime highlighted increasing pressure on terminal facilities, runway slots, and ground handling operations, particularly in Europe and Asia.
ACI urged governments to accelerate airport expansion, modernize air traffic systems, and invest in digital solutions to improve passenger flow and efficiency.
