SINGAPORE - In a major setback to Changi Airport's overseas ambitions, it has lost a key contract to operate and manage an airport in Saudi Arabia.

The termination notice served on Wednesday (Feb 21) comes less than a year after Changi Airports International (CAI) - Changi's foreign investment and airport management arm - and Saudi Naval Services were awarded a 20-year contract to operate King Abdulaziz International Airport (KAIA) in Jeddah, Saudi Arabia.
