CHINA AND SOUTH KOREA

South Korea

Korean Air, Incheon's hub and a strong aerostructures and space-launch industry, with early urban air mobility trials.

Market overview

South Korea's air market reached a record 124.8 million passengers in 2025, up 3.9% and above the 2019 peak. International travel drove the growth, rising 6.3% to 94.5 million, while domestic traffic fell 2.8% to 30.2 million. Incheon, the main gateway, handled 74.1 million international passengers and 2.95 million tonnes of international cargo. Its fourth construction phase, finished in November 2024, raised capacity to about 106 million passengers a year. The airline sector is consolidating. Korean Air plans to complete its merger with Asiana on 17 December 2026, moving Asiana's aircraft onto its own operator certificate. In August 2025 it ordered 103 Boeing aircraft worth about US$36.5 billion, plus a US$13.7 billion engines and services deal with GE Aerospace, and about four-fifths of those aircraft are replacements. For suppliers, the merger means fleet and cabin harmonisation, IT and system integration, and retraining. Korea's own aerostructures and parts makers offer partnership routes into global programmes.
