Changi Airport has rolled out a $100-million assistance package to help airlines and other partners cope with tough times.

The new one-year initiative also aims to boost passenger traffic and strengthen Changi's hub status, as well as improve efficiency at the aiport, Changi Airport Group (CAG) said on Thursday.

From next month, all airlines operating at Changi Airport will enjoy an across-the-board reduction in operating costs including a 50 per cent rebate on aircraft parking fees and a 15 per cent discount on aerobridge charges.

Changi will reward airlines for growing transfer traffic at Changi Airport and work with carriers who want to raise operational efficiency.

To stimulate traffic demand, CAG will invest in marketing campaigns to promote Singapore in major markets like Australia, China, India, Indonesia and Russia.

Recognising the increasing manpower challenges faced by the ground handling and security agencies at Changi Airport, CAG said efforts will be stepped up to help the firms raise productivity levels.

The airport will commit funds to support enhancements that reduce these agencies' manpower requirements and optimise the efficiency of their operations at Changi.

CAG chief executive officer, Lee Seow Hiang, said: "CAG values the deep partnerships we have with our airline partners and we are cognisant of the market conditions faced by them. While we cannot iron out the volatilities of the industry cycle, we believe that GAIN (Growth and Assistance Incentive) will provide helpful temporary cost relief as airlines implement the necessary measures needed to adjust to the evolving market environment."

He added: "At the same time, we believe the programme provides encouraging opportunities for our partners to collaborate with us to explore new ideas and initiatives - whether to stimulate travel demand or to boost productivity - that will collectively position us strongly for the next wave of growth."
