JCDecaux is the largest global outdoor advertising company, having secured 10-year exclusive contracts with Sharjah International Airport and Dubai International Airport. Airports provide an effective advertising medium, as travelers are a captive audience that spends an average of 2 hours and 25 minutes in the airport prior to departure. Being present at the airport allows brands to reach decision makers and executives, as 73% of frequent travelers fall into this category. With 4.9 billion passengers in 2008, airports allow advertisers to precisely target their intended audience.
