CHICAGO, May 8 (UPI) -- Chicago Midway International Airport Thursday began using a security checkpoint system that separates experienced travelers from beginners, officials said.
Color coded signs, similar to those at ski resorts, direct passengers to choose which security line to stand in based on how much flying experience they have, the Chicago Tribune reported Thursday.
A green circle marks the line for inexperienced passengers, a blue square is for those with an intermediate level of experience and a black diamond line is for pro travelers.
It is reported the separate lines are part of an effort cut down airport wait times and reduce stress for travelers and security workers.
In case travelers aren't familiar with ski symbols, text has been added to the signs to explain their meaning.
Since the system was tested out in Denver and Salt Lake City, it has been implemented at about a dozen airports throughout the country, the Tribune reported.
