“The [Federal Aviation Administration] requests that airports work with their concessionaires to help avoid” unsafe behavior, agency chief Steve Dickson wrote in a letter Tuesday to airport managers. “Even though FAA regulations specifically prohibit the consumption of alcohol aboard an aircraft that is not served by the airline, we have received reports that some airport concessionaires have offered alcohol ‘to go,’ and passengers believe they can carry that alcohol onto their flights or they become inebriated during the boarding process.”

Dickson suggested airports work to prevent passengers from boarding planes with alcohol through signage warning against doing so, public service announcements, and informing airport bars and restaurants of the prohibition on “to go” drinks.
