(Portland, OR) -- The newly remodeled main terminal at Portland International Airport is now open. The nine-acre ceiling is made of wood from 11 forests within 300 miles of the airport. There are 72 trees, five-thousand plants, and 49 skylights. It's designed to make travelers feel like they're walking through a mini forest. New restaurants and shops are open in the area before screening. Ticketing is set up in an island-style. TSA has more lanes and a system that allows three people at a time to place bags on conveyors that go through scanners. There are two locations with new carpet that's made with the old design travelers like to use for foot selfies.
