ONT terminal information
Ontario International Airport currently operates passenger Terminals 2 and 4 plus a separate International Arrivals Facility. Terminal 3 is a future development project rather than an active passenger terminal, so travelers should use the airline/flight information to confirm whether Terminal 2 or 4 is required.
Official parking at Ontario International Airport
Official parking lots are positioned around Terminals 2 and 4, with Lot 1 serving the International Arrivals Facility area and valet also available. The closest lots allow a short walk to the terminals; other products may use airport shuttles.
Rental cars and ground transportation
A separate Rental Car Center is connected to Terminals 2 and 4 by free airport shuttle buses. Taxis, rideshare and other ground transportation use designated pickup zones outside each active terminal.
Passenger services and terminal facilities
ONT provides passenger Wi-Fi, more than 20 food and retail locations across the two terminals, charging and standard family/passenger amenities. International arrivals have their own processing facility.
Accessibility and assisted travel at ONT
Accessible passenger pickup/drop-off and parking are provided at the terminal facilities, with elevators and accessible routes throughout. Airport shuttle buses and airline assistance support passengers with reduced mobility.

If you reserve an independent/off-airport parking facility or a hotel parking package, use the separate address and arrival instructions in that confirmation rather than navigating to the passenger terminal by default.
Information source and current-travel note
Official ONT active-terminal, parking, rental-car, concessions and accessibility information reviewed August 2026; future Terminal 3 plans were not described as current operations.
Provider-specific parking prices, opening hours, shuttle frequency, cancellation conditions and whether you keep your keys are intentionally left to the live booking result and confirmation because those details can vary by date and facility.
