​By 2025, aviation in Asia-Pacific region is expected to support 72 million jobs and $1,340 billion in GDP. That's almost double that of today. But aviation's potential economic contribution to the region is by no means guaranteed if the infrastructure and policies are not in place to support the anticipated traffic growth.
