Connecting flights often yield the cheapest economy fares from Ontario International Airport (ONT), especially for longer distances. However, they add total travel time and connection risk.

Legacy carriers (Delta, United, American, Alaska) provide more frequent schedules and bundled services that may reduce ancillary costs when traveling with bags or needing upgrades.
Spring shoulder seasons (April, September) are best for cheap economy fares from Ontario International Airport (ONT). Summer (June–August) is peak and pricier — book months ahead. Winter holidays (late November–December) spike prices; consider early January for bargains.
