What terminal is Turkish Airlines at ORD? ORD Airport's international terminal, Terminal 5, is where Turkish Airlines uses its space. The majority of international arrivals and departures are handled by this state-of-the-art facility, which serves as the terminal for Turkish Airlines' direct flights between Chicago and Istanbul. Currency exchange, duty-free shopping, dining options, and cozy seating places are just a few of the facilities available at T5. Turkish Airlines usually departs from gates in the M Concourse and passengers can check in at booths at the entrance of T5. For a more upscale experience, eligible passengers—including those flying in business class—can enter the Swissport Lounge. To guarantee enough time for check-in, security screening, and passport control, travelers are encouraged to arrive at least three hours before departure, as is the case with the majority of foreign flights.
