Large events that often drive up economy fares from Ontario International Airport (ONT) include: Los Angeles major events (award shows and sports playoffs) in February–June, Coachella in April, Comic-Con in July, summer concerts and fairs in June–August, and holiday events in late December. Additionally, NCAA tournaments, major conventions, and business conferences in downtown Los Angeles or Anaheim can temporarily increase demand and raise economy fares.

The best time to fly from Ontario International Airport (ONT) for cheap economy fares is typically January, February, and September, with midweek departures (Tuesday–Thursday) and off-peak hours (early morning or late night) offering lower prices. Avoid high-demand windows like summer months (June–August), Thanksgiving, and late December unless you book well in advance. For international economy trips, aim to book 2–6 months ahead; for domestic economy, 1–3 months is often optimal. Use fare alerts, flexible-date searches, and compare alternate nearby airports to secure the best deals.

Direct nonstop flights from ONT are usually faster and more convenient but can cost more in economy compared with connecting options, especially on longer routes. Connecting flights often offer cheaper economy fares by leveraging lower-cost hubs or off-peak routing, but add travel time and potential connection risk. If prioritizing the cheapest economy fare, consider one-stop itineraries with reasonable layover times, and allow 60–90 minutes for domestic connections and 2+ hours for international transfers. Always weigh total travel time, baggage transfer policies, and potential fees when choosing between direct and connecting economy options.

For the cheapest economy fares, compare basic economy across carriers, factor in ancillary fees, and consider bundled fares when baggage or seat selection is needed. CTA: Compare current economy offers from each carrier and book the cheapest fare that fits your baggage and schedule needs.

Winter: Book early for holiday travel and use carry-on only strategies to avoid checked bag fees; expect occasional weather-related delays on longer routes.

Summer: Reserve seats months in advance and travel midweek to reduce economy fares; plan for heavier traffic to and from major nearby cities like Los Angeles and San Diego.
