Checking in to flight home from Lihue was a bit time-consuming and chaotic. We had to remind ourselves this is a regional airport, not LAX. Other than that, experience was pleasant, and we were happy to fly 'the only airlines that still serves complimentary food and beverages'.

Why You Should Take a Flight to Ontario, CA

Once a health resort and a citrus farming hotspot, Ontario, 50 miles east of Los Angeles, is a destination that mixes the city thrills of LA with the chance to escape to the wilds of the Californian desert.

Known as the gateway to southern California, Ontario is within striking distance of attractions including Disneyland, Palm Springs, San Diego Zoo and Lake Arrowhead. And while it makes the perfect base for a SoCal adventure it also has attractions of its own, with museums, malls, culture and good weather all year round.

When to Book Flights to Ontario

There is no bad time to visit Ontario, the summers are warm and the winters mild. The area is busiest between June and September and November and December, so think ahead if you want to visit then.

Spring is a good time to travel, with average temperatures above 70°F and fewer visitors.

Ontario is busy around Thanksgiving, Christmas and July 4th. It also hosts a popular quilt festival in January and the Route 66 Cruisin’ Reunion classic car show in September.

With regular flights to more than a dozen US cities, finding cheap flights to Ontario should not be difficult and when booking with Orbitz there are plenty of ways to find the best deals

What Are the Must-Sees in Ontario?

With southern California beckoning it could be easy to overlook the attractions in Ontario itself, but the city is worth exploring. Foodies will love the Graber Olive House, the oldest operating facility in the country, founded in 1894. Canning season runs for two months during fall, but the facility is open all year round.

Ontario’s Museum of History and Art has fascinating displays that shine a light on the farming and industrial heritage of the area and runs a regular program of workshops and outreach events.

If it’s retail therapy you are after, then visit Ontario Mills Mall, which is one of the largest on the west coast.
