Terminal C, designed by Grad Associates was completed in 1988. Terminal C is exclusively operated by and for United Airlines and its regional carrier United Express for their global hub at EWR. The terminal has two ticketing levels, one for international check-in and one for domestic check-in. The main terminal building for Terminal C was built alongside Terminals A and B in the 1970s, but lay dormant until People Express Airlines took it over as a replacement for the former North Terminal when the airline's hub there outgrew the old facility. Upon opening, Terminal C had 41 gates, one departures level, one arrivals level, and an underground parking garage.
