Arriving at Ontario (ONT) FAQs
Arriving in Economy Class (ECO) usually means lower base fares with more restrictive baggage and seat selection policies compared to premium cabins.

These destinations often appear in route maps for inexpensive, short-haul travel and can offer convenient connections to broader national and international networks. Use city-based searches and low-fare calendars to find the best economy deals.
To find the cheapest economy fare for a targeted arrival city, use flexible-date search, set fare alerts on multiple platforms, and compare low-cost and legacy carriers.

Use month-aware searches and subscribe to alerts for the months you plan to travel to secure the cheapest economy arrivals.
Immigration and customs processing for Economy Class (ECO) passengers is the same as for other classes—processing time depends on airport volume, staffing, and whether you have expedited options like Global Entry. Arrive with completed forms, passports, and documentation to speed processing, and check airport arrival maps for customs area guidance. Allow extra time for baggage claim and ground transport after clearing customs.
No—onward ground transportation options (rental cars, public transit, ride-hailing) are available regardless of cabin class; however, arrival times and baggage volume can impact convenience. Budget travelers may prioritize shuttle services and public transit to cut costs, while those with large luggage might prefer taxis or car rentals. Plan your ground transfer in advance for the best rates and fastest connections.
