Popular Flight Destinations and Routes
You’ll find a bunch of nonstop and connecting flights from Ontario International Airport to big U.S. and international cities. There’s a mix for both business and leisure travel.
Direct Flights to Major Cities
Ontario Airport’s got nonstop flights to places like Atlanta, Charlotte, Chicago (Midway), and Austin. These direct flights help you skip layovers and get there faster, whether it’s for work or fun.
Internationally, you can fly nonstop to Guadalajara in Mexico and Taipei, Taiwan. Those are some of the longest nonstop flights from Ontario, so you’re covered for big trips.
Southwest Airlines, Delta, American, and China Airlines are the main carriers for these routes. That means multiple daily flights and plenty of availability.
Nonstop and Indirect Flight Options
Not every destination has a nonstop, though. For some places, you’ll need a connection.
For instance, if you’re going to San Francisco, you might find a cheaper or more frequent flight with a layover instead of a direct one.
Usually, these connections run through big hubs like Los Angeles or Dallas. Sometimes it’s worth it if the direct flights don’t fit your schedule or your budget.
Just double-check the layover times. Indirect flights can add hours to your day, and nobody wants to be stuck in an airport longer than necessary.
Return Flight Booking Advice
When booking your return, try to grab a round-trip ticket with the same airline. It can lower your fare and make any changes simpler if things come up.
Look for flights that give you enough time to get back without feeling rushed, especially if there’s a layover involved.
If you fly indirect one way, maybe see if there’s a direct flight home. It’s usually less stressful after a long trip. Always compare both legs before you click “buy.”
Travel Planning and Booking Tools
Booking flights from Ontario can be less stressful if you use the right tools. You can track prices and find the best dates without a ton of effort.
Using Skyscanner and Setting Price Alerts
Skyscanner’s a free flight search engine that helps you find cheap tickets from Ontario. Just pop in your destination and dates, and it’ll show you options from a bunch of airlines.
One handy thing: you can set price alerts. You’ll get emails if the ticket price for your route changes, so you don’t have to check every day. After you search, just click to set an alert and enter your email.
This works well for popular airlines like Southwest and Frontier. You’ll see deals pop up as soon as they’re available.
Flight Calendar for Best Deals
A flight calendar shows prices for each day of the month, so you can spot the cheapest days to fly. Skyscanner has this feature, and it’s surprisingly useful.
Instead of locking in dates before searching, you can scan entire weeks or months at a glance. If you’re flexible, look for lower prices midweek or during off-peak hours.
Flight calendars take the guesswork out and help you squeeze the best value from your trip.
