The Civil Aviation Authority of Singapore has made an offer to four airlines to move their operations to Terminal 3.
The four airlines, China Eastern Airlines, Jet Airways, Qatar Airways and United Airlines, will join Singapore Airlines in operating from T3.
Terminal 3, currently undergoing tests and trials, opens for flight operations on the 9th of January next year.
CAAS says the decision to offer the four airlines to move their operations to the new terminal was reached after careful and detailed assessments.
It had earlier written to all airlines at Changi Airport to check which of them would be interested to be considered to operate from T3.
Dialogues were also held with airlines to address their questions and concerns about moving their operations.
CAAS says the four new airlines moving their operations to T3 will also enable Changi Airport to spread out usage of the three terminals in a balanced manner
