Some travelers flying in and out of O'Hare International Airport are being advised to give themselves extra travel time starting this week.
The Chicago Department of Aviation says the "people mover" train that takes travelers and employees between economy parking lots and the terminals will be shut down beginning Monday.
Instead, shuttle buses will transport people between the terminals and both parking lot E -- also known as the "Kiss n' Fly Lot" -- and lot F.
The train will continue to operate between airport terminals.
The service changes are to accommodate a construction project.
