Combine time-of-day flexibility with price alerts to capture the best deals.
For winter holidays (late November through early January), book economy flights from Ontario International Airport (ONT) 2–4 months in advance to secure reasonable rates and preferred schedules.

Arriving at Ontario (ONT) FAQs
The label 'Cheapest Economy Fare (CHEAPEST)' indicates the lowest published economy ticket price for an arrival route, typically excluding optional add-ons like checked bags and seat selection.

These routes often have competitive economy pricing due to high volume and low-cost carrier competition. Use destination-specific searches to find the lowest economy fares for each city.
Maximize value by comparing total trip costs — include baggage, seat selection, and change fees — instead of just the base fare. Book during off-peak times, use flexible-date searches, and consider bundled offers that include carry-on or checked luggage if you need them. Sign up for fare alerts, use airline miles or credit card points, and consider nearby airports for better deals.
Yes, September often offers some of the year's cheapest economy arrival fares as travel demand drops after Labor Day. This is a prime month for discounted flights into major cities and popular fall destinations, especially if you fly midweek or at off-peak hours. Use September-specific fare calendars and flexible-date searches to capture these savings.
Cheapest economy arrival tickets often come with restrictions such as non-refundable fares, change fees, seat selection charges, and limited or no checked-bag allowance. They may also have limited frequent-flyer accrual or blackout dates. Review the fare rules at booking and consider paying a little more for a bundled economy class if you need flexibility.
Arrival times can impact the overall price and convenience of cheapest economy fares; red-eye and very early morning arrivals can be cheaper but may complicate ground transport and connections. If you have a tight connection, the lowest economy fares may not include protection for missed connections, so budget extra time or select a slightly higher fare that offers better rebooking options. Balance cost savings with the risk of missed connections.
