Ontario International Airport (ONT) is the preferred alternative for travelers looking to avoid the heavy congestion of LAX. Located in the heart of the Inland Empire, ONT offers a modern and efficient environment just 35 miles east of downtown Los Angeles. Whether you are visiting for the world-class shopping at Ontario Mills, attending a convention, or heading to the nearby mountain resorts, finding cheap flights to Ontario is simple with the right planning. This guide provides essential tips and route information to help you secure the best ONT flight deals.
As one of the fastest-growing airports in the region, Ontario sees high competition among airlines, which often leads to lower fares for travelers. To land the best rates, aim to book your tickets at least 3 to 5 weeks in advance. For those traveling from Western hubs like Seattle, Denver, or Phoenix, carriers frequently offer promotional fares for midweek departures.
Pro Tip: Late spring and early fall are often the "sweet spot" months for Ontario travel. During these times, airfare averages are lower than the summer peak, and the weather is ideal for exploring regional parks and outdoor attractions.
