Airport Information & Terminals
ORD: Chicago airport system. Chicago flights commonly use O'Hare or Midway. O'Hare is a huge hub with rail access; Midway can be easier for some city-side trips. Winter weather and traffic should be part of the booking decision.
BUF: Buffalo airport. Buffalo airport transfer should be matched to the exact hotel, suburb or meeting area. Rail can work well for light luggage, but late arrivals, winter weather and family baggage often make a direct cab or booked transfer easier.
