I will be travelling on United from Vancouver (YVR) to Baltimore (BWI) with a 1 hour 25 minute stop in Chicago (ORD). I heard that connecting flights in the US will require passengers to go through customs, get their luggage, and then check back in again. However, I also heard that passengers travelling from Vancouver will have already completed all US customs at YVR. My question is, will I need to go through customs again in Chicago? Or can I just go straight to my departure gate in Chicago? Also, will my checked luggage make it in time? Thanks!
