According to the survey carried out by the Airport Show ahead of the next month's inaugural Global Airport Leaders' Forum (GALF), 64.4 per cent of respondents voted online for the Middle East region, followed by the Asia Pacific with 16.7 per cent, Central Asia and Africa regions with 5.2 per cent each and Europe with 3.4 per cent.
Airport Show is a leading airport event for the Middle East, North Africa and Indian subcontinent region.
"An investment of USD 90 billion is projected to go into aviation industry in the Middle East by the year 2020," it added.
"Senior executives from across the international aviation industry have contributed to the survey and we believe the survey results will contribute significantly to the important discussions at the Global Airport Leaders' Forum and help highlight the key challenges and opportunities industry leaders face today," said Daniyal Qureshi, event director of the Airport Show.
Over 88 per cent of survey participants agreed that satisfactory sustainable airport growth could be achieved if leadership and stakeholders work together to develop a collaborative aviation policy.
