Understanding those differences makes it easier to pick what works best for you.
Frontier Airlines Overview
Frontier Airlines is a popular low-cost carrier with lots of routes out of Thornton. They usually have some of the cheapest fares around.
Frontier uses an ultra-low-cost model, so the base ticket price is pretty low. But you’ll pay extra for bags, picking your seat, or even a snack.
The airline runs a newer fleet and covers key cities across the U.S. If you book early and don’t pack much, you’ll probably get a great deal.
Their policies really encourage you to stick to a carry-on. Otherwise, those bag fees can add up fast.

That’s a big plus if you’re traveling with more stuff. Southwest flies often from Denver International Airport, which is just a short drive from Thornton.

Allegiant usually offers nonstop flights to leisure destinations. If your plans line up with their schedule, it’s a solid pick.
Watch out for extra fees, though—things like carry-ons and seat choices add up. Their flights don’t run as often as some other airlines, so you’ll want to check their schedule closely.
The airline keeps base fares low, but just about everything else is an add-on.
Comparing Flight Routes and Destinations

Knowing which airline flies where really helps you plan.
Nonstop and Direct Routes
Nonstop flights from Thornton are a big time-saver. The plane just goes straight to your destination—no stops.
Frontier Airlines, one of the main budget carriers here, offers several nonstop flights to major cities. For example, you can fly nonstop to Denver International Airport and other hubs close to Thornton.
Direct flights might have a stop, but you don’t have to change planes. It’s a little less convenient, but it opens up more destinations.

Tips for Booking Cheap Flights from Thornton
Getting the best price on flights from Thornton really depends on when and how you book. Timing and a little research can save you a decent chunk of change.
Booking Strategies for Best Prices
To score good flight deals, try booking your tickets on weekdays—especially Sundays. There’s data showing you can save between 6% and 13% by skipping the weekends.
Check flight comparison sites so you can see what multiple airlines are offering. That way, you’ll spot the cheapest options faster.
Booking well in advance usually helps—think 3 to 5 weeks before your trip. Last-minute deals are pretty rare and, honestly, often more expensive.
If your dates are flexible, look for one-way tickets. Sometimes booking two one-ways with different airlines is cheaper than a round trip.
And don’t forget to sign up for airline newsletters. They’ll send out exclusive discounts that you won’t find anywhere else.
Seasonal Travel Considerations
Flight prices from Thornton shift a lot depending on the time of year. You’ll usually spot cheaper fares in the late fall or winter—unless you’re aiming for the holidays, of course.
If you can, steer clear of major holidays or school breaks. That’s when prices really jump.
Booking early for summer or holiday trips? That’s smart. Airlines love to bump up prices as seats disappear.
Mid-week flights, like on a Tuesday or Wednesday, are often less expensive. It’s not a rule, but it’s a pattern that pops up a lot.
Early morning or late-night flights can also save you some cash. Not everyone’s a fan of those hours, but your wallet might thank you.
