“Airport advertising is big business nationally. A 2011 Scarborough survey on behalf of Clear Channel Outdoor Holding's airport advertising division found business frequent fliers are 83% more likely than all U.S. adults to be the first to try or to buy new products and services.
Airports have a "high dwell time environment, and deliver a captive audience," the survey found. It also said about three in four frequent fliers and business frequent fliers notice airport advertising, and take time to read the message. Frequent fliers were defined as adults who took three or more round-trip flights in the past year. Business frequent fliers took three or more round-trip flights per year for business.”
