Domestic-to-Domestic: 40 min. Domestic-to-International: 65 min. International-to-Domestic: 65 min. International-to-International: 75 min. These are the shortest layovers airlines will sell at Ontario International.
Is ONT easy to connect through?
Ontario International is a small, low-stress airport in the Inland Empire that primarily handles domestic point-to-point traffic with a limited number of Mexico routes on Volaris. Because it's not a true hub for any airline and traffic volumes are modest, security lines and terminal transfers are usually quick, but there is no automated people-mover so connections between the two terminal buildings require a short walk or shuttle ride. Terminal 2 and Terminal 4 sit a few hundred yards apart and are connected by an outdoor walkway as well as a periodic shuttle bus that circles the terminal loop road. Passengers connecting between the two terminals must exit security, walk or ride the shuttle, and re-clear TSA screening, since there is no sterile connector between the buildings.
