He said the terminal, with the state-of-the-art facilities, could fulfil all the needs for commercial flight operations and cater to the needs of up to 14 million passengers.
Abdul Rahim said the transfer of AirAsia's operations to Terminal 1 would provide better flight connectivity to the passengers.
It could also avoid passengers from missing their flight and reduce the cost burden on the passengers in hiring taxis to go to Terminal 2 or being trapped in traffic jams while on transit flight, he said here, Saturday.
Furthermore, he said, all the design and facilities at Terminal 1 such as the aerobridge had been provided as required.
As such, Abdul Rahim said, there was no reason for AirAsia not to move to Terminal 1 which he believed would not adversely affect operations but would probably lead to greater efficiency.
Previously, AsiaAsia had appealed to the Transport Ministry to continue its operations at the Terminal 2 KKIA although it had given its commitment to move to the Terminal 1 in mid-June this year.
Last month, AirAsia's Chief Executive Officer Datuk Seri Tony Fernandes said the airline was hesitant about moving out from Terminal 2 to Terminal 1 KKIA which was recently expanded because the cost would rise, thus forcing it to reduce the number of flights and causing Sabah to lose about one million tourists.
