November has a mix of off-peak days and Thanksgiving peak travel; avoid peak travel days around Thanksgiving (Wednesday–Sunday) and consider arriving or departing a couple of days earlier or later to save. Use price-tracking tools and check airlines’ seasonal sales typically released in September–October.
For domestic flights from Ontario International Airport (ONT), arrive at least 90 minutes before departure for standard economy travel and two hours if you have checked baggage, need to park and shuttle to the terminal, or are traveling during a busy holiday month like December. Weekends and peak holiday mornings can have longer security lines, so plan extra buffer time if traveling during high-demand months.

Arriving at Ontario (ONT) FAQs
A Cheapest Economy (ECONOMY) fare typically includes a basic seat and limited flexibility, often excluding free checked baggage, seat selection, and sometimes carry-on allowances depending on the carrier. These fares are optimized for travelers prioritizing the lowest price; review the airline's fare rules carefully before booking to avoid unexpected fees at the airport.
Carry-on policies vary: some airlines allow a personal item only with the cheapest economy (ECONOMY) fare, while others include one small carry-on. Always verify the specific airline’s baggage policy before travel—soft-sided underseat items are generally accepted but overhead bin space may require an additional fee on low-cost carriers.
You can often upgrade from the cheapest economy (ECONOMY) fare by paying for a fare class upgrade online, purchasing an exit-row or premium economy seat at check-in, or using frequent flyer miles. During the month of travel—especially in off-peak months like September—last-minute upgrade offers may be cheaper, but availability is limited so consider upgrading earlier if seat choice is important.
Cheapest Economy (ECONOMY) tickets are usually non-refundable and have strict or no-change policies without fees; however, some carriers now offer basic change options for a fee or under certain fare bundles. Always check the airline’s fare rules and consider purchasing travel insurance or a refundable fare if you need flexibility, especially for travel during uncertain months like December.
Most carriers charge extra for seat selection and exit-row or extra-legroom seats when you book the cheapest economy (ECONOMY) fare. If legroom is a priority, compare the total cost including seat fees across airlines—sometimes paying slightly more upfront for a higher economy fare with included seat selection is cheaper than adding multiple ancillary fees.
Check in online as early as airline allows—usually 24 hours before departure—to secure free or low-cost seat options and avoid lines at the airport. If you must check bags, arrive at the airport early (90–120 minutes for domestic, 2–3 hours for international) especially during busy months such as July and December when terminals are more crowded.
