The best time to fly cheap economy from Ontario International Airport (ONT) is during shoulder seasons—September through early November and January through early March—when demand and fares are lowest. Mid-week departures (Tuesday–Thursday) and early-morning flights typically offer the cheapest economy prices. Avoid peak travel windows such as July and late-December unless you book months in advance.

Direct flights from Ontario International Airport (ONT) save time and reduce the risk of missed connections but are often priced higher than connecting options. Connecting economy flights can be significantly cheaper, especially when routed through hubs like Los Angeles (LAX), Phoenix (PHX) or Salt Lake City (SLC), but add total travel time and potential layover risk. Choose direct flights for time-sensitive travel and connections when maximizing savings is the priority.

Extra Tips

• For cheapest economy fares, search connecting options if you have flexible arrival/departure windows.
• Allow generous layover time when booking separate tickets to reduce connection risk.
• Consider the total door-to-door time and costs (including transfers) when choosing direct vs connecting.

Key carriers at Ontario International Airport (ONT) include Southwest Airlines, Spirit Airlines, Frontier, Alaska Airlines, American Airlines and seasonal Delta service.

Compare on-time performance, ancillary fees, and total trip cost when selecting the cheapest economy option.

Tips

• For cheapest total cost, calculate base fare plus expected ancillary fees before booking.
• Use fare bundles and loyalty programs to offset economy costs for frequent routes.
• Check refund/change policies for cheapest economy fare types to avoid surprise fees.
