Wilmington International Airport seeks feedback! ILM has developed a survey in order to gather passenger feedback. The feedback will help inform ILM about ways in which the airport can develop concessions, amenities and services that best meet the needs of ILM’s travelers. The survey is open through 8/20/19. As part of the survey, respondents have an opportunity to enter a drawing to receive a $300 airline gift card or up to $300 worth of miles for American Airlines, United Airlines, OR Delta Air Lines.
