It’s just an airport really. All i remember is that some of the guards were useless in helping me find my way (one told me to go back to my electric ticket station when i asked fr directions to the terminal. like i was on time out. not a threat or anything, just an annoying kid who who got sent to the corner for annoying mom) the most helpful person was this young dude who was helping everyone out. What’s nice is that the red line is attached to the airport, so you don’t have to wander the cold frozen streets of chicago to find the public transportation.
