Inouye International Airport, which is in the midst of a modernization project that he says will lead to an open, safe, efficient and even pleasant facility. That means clean restrooms, lots of food and retail options, room to stretch and walk around, places to relax before and between flights, clear signage and easy access to rental cars and public transportation.
