The document discusses key challenges facing airport operators regarding airport expansions. It notes that Asia Pacific is projected to overtake North America as the top region for air traffic by 2030 due to rapid urbanization and economic growth in developing countries. However, airport expansions require careful planning to address issues such as return on investment versus cost of capital, aligning infrastructure with airline fleet and passenger growth plans, implementing strong security measures while maintaining passenger experience, and balancing economic benefits with environmental concerns. The document promotes attending the Airfield Engineering and Asset Maintenance 2013 conference to learn best practices for ensuring operational efficiency and safety in airfield expansions and maintenance.
