ONT Airport Transportation to Fullerton: Options to Compare

From ONT, the drive to Willow Tree Lodge takes about 41 minutes. That gives you a starting point when comparing a direct car trip with transit connections; actual journey conditions can affect the trip.

Ontario International Airport identifies several ground-transport categories, but those options do not establish a direct connection to Fullerton. Check the route and any transfers for your destination before setting out. If you’re arriving by train in Fullerton instead, station arrival details can help you plan the final part of the trip.

A rental car gives you a road-based option from ONT, while the airport also offers ride apps, taxis, and limousines. ONT provides a free shuttle between its passenger terminals and the Rental Car Center at 3450 East Airport Drive, near Haven Avenue.

For a rental, first follow the airport signs for the Rental Car Center and use its shuttle from the terminal. The center’s address is 3450 E. Airport Drive, Ontario, CA 91761; Terminal 2 is at 2500 E. Airport Drive, Ontario, CA 91761. Rental providers and services can change, so check the official site before you go.

Rideshare is another option if you don’t want to drive yourself. ONT says arriving passengers are dropped at their appropriate terminal; departing passengers meet drivers at the Rideshare Pick Up signs outside each terminal.

Request a ride after collecting your luggage, pay through the provider’s app, and confirm the driver’s name, vehicle make and model, and license plate before getting in. Fares vary by destination, time of day, and anticipated traffic.

Public transit from ONT can involve a shuttle connection: ONT Connect runs nonstop between the airport and Rancho Cucamonga Metrolink Station, serving Terminals 2 and 4. That connection is to the station, not a stated direct bus or rail trip to Fullerton.

Passengers boarding ONT Connect at the airport should follow signs to the stop east of the terminals, to the right when exiting. A valid Metrolink ticket with ONT Connect as the origin or destination includes a free ride on the shuttle. Check the operator’s site before traveling for current service details.

ONT also identifies bus and rail transportation among its ground-transport options. To plan a transit journey to Fullerton, check which provider serves each leg and whether you’ll need to transfer; the airport’s general options do not confirm a single direct route.

A rail leg into town may end at Fullerton Station, where the Fullerton Station arrival guide covers arrival details.

The option to compare depends on whether you want to drive, arrange a pickup, or connect through transit. For a car, account for the trip to the Rental Car Center and its terminal shuttle.

For rideshare, collect your luggage before requesting the trip and use the marked pickup area. For public transit, verify the complete route to Fullerton, including the connection from ONT Connect to your next service.

If you’re planning time in town, this one-day route through downtown Fullerton offers a way to organize a visit.
