Best time to fly from Ontario International Airport (ONT) to Miami International Airport (MIA) in September is typically midweek (Tuesday–Thursday) and during early-morning or late-evening departures. These times often yield lower fares and less crowded terminals, especially when looking for cheap flights. For the best balance of price and schedule flexibility, book 3–8 weeks ahead and avoid peak holiday dates like Labor Day weekend unless you need those specific travel dates.
Choosing nonstop versus connecting flights from Ontario International Airport (ONT) to Miami International Airport (MIA) involves trade-offs. Nonstop flights save time and reduce the chance of missed connections, often costing more but convenient for business travelers or families; connecting flights can be significantly cheaper and offer more schedule options but add total travel time and risk during hurricane season. For September travel, weigh savings against potential weather delays—if you have tight schedules or multiple short layovers, prefer nonstop when available.
Compare carriers for ONT to MIA travel in September: ultra-low-cost carriers (ULCCs) offer the lowest base fares but charge extra for baggage, seat selection, and sometimes carry-on; legacy carriers (American, Delta, United) provide more included services, better disruption support, and extensive connecting options. Key considerations: total ticket price including fees, loyalty program benefits, on-time performance, baggage allowances, and rebooking policies during hurricane season. If you prioritize price, ULCCs may be best; if you need reliability and perks, consider a legacy carrier.
September is peak Atlantic hurricane season and the shoulder travel season for Florida. Travelers flying from Ontario International Airport (ONT) to Miami International Airport (MIA) should prioritize flexible tickets, consider travel insurance with weather coverage, and monitor National Hurricane Center forecasts. Pack for hot, humid weather with lightweight clothing, bring a compact umbrella, and plan for potential delays by leaving buffer time for connections or ground transport. For airport convenience, use Ontario’s shorter security lines when possible and pre-book rideshares or rental cars for arrival at MIA.

Finding cheap flights from Ontario International Airport (ONT) to Miami International Airport (MIA) in September is realistic if you use flexible dates and compare budget and legacy carriers. Primary tactics: search midweek travel (Tuesday–Thursday), book 3–8 weeks in advance, enable fare alerts, and use incognito or fare-aggregator comparisons to identify flash sales.
