Top tips for finding a cheap flight out of Denver (DEN)

Book your trip during the Goldilocks Window

When it comes to booking flights, there are certain windows when you’re more likely to get a cheaper flight. For domestic travel, we suggest booking flights 1-3 months in advance. For international trips, bump that up to 2-8 months in advance. This is what we call the Goldilocks Window—the not-too-early, not-too-late sweet spot when cheap fares are most apt to crop up.

If you don’t have the luxury of being flexible with your travel dates, however, or you have to fly during the high season, we’d recommend looking at fares even further ahead of time. Travelers who want to fly during the December holidays, for instance, should start looking at airfare in July.

It’s also important to note that while last-minute deals do happen from time to time, prices are more likely to jump at the 21-day, 14-day, and 7-day marks before a flight, so be sure to lock in your fare before those dates if you can.

Consider trying the Greek Islands Trick

Sometimes the place you really want to go is a destination that always seems to be on the expensive side of the airfare spectrum. If you have your heart set on Santorini, for example, it’s easy to balk at fares from Denver in the $1,500 range. Before ditching your travel dreams, though, consider flying from Denver to London for around $700 roundtrip. Even if you add a $200 flight from London to Santorini, you still save a few hundred dollars. While we call this the Greek Islands Trick, it’s a technique that can work just as well for itineraries all over the world.

The idea is to find the cheapest fare that gets you relatively close to where you ultimately want to end up—in this case, getting from Denver to Europe. Then you need to find a separate transportation mode to get you the rest of the way. It could be a low-cost flight or even a train or ferry. And, yes, it does take a bit more work on your part. But it’s worth looking into since it can save you quite a bit of cash.

Look at alternate airports nearby (or not so nearby)

If you live in or near Denver, you may never think about flying out of any other airport besides DEN. But all it takes is a jaw-dropping deal on a long-haul flight from another airport (how does $63 from Atlanta to Chile roundtrip sound?) to make you reconsider your departure location.

Unexpected deals pop up occasionally that, while they may not be from your closest airport, might mean huge savings. Booking that super cheap flight from Atlanta to Chile means booking a separate flight from Denver to Atlanta, sure, but when the latter might cost less than $100, you’re still getting a screaming deal on a Chile vacation.

Travel when it’s cheaper to fly

Some periods are understood as more popular travel seasons. During the summer, for instance, families can more readily travel because the kids are out of school—and even if school schedules don’t factor into your holiday travel plans, summer weather is usually a big draw for vacationers. With demand for flights higher during peak seasons like summer, airlines routinely raise fares.

To save a little money, consider traveling during a destination's shoulder seasons—usually spring and fall, sitting between high and low seasons on both ends. Prices will be lower than during the peak season, and the weather will usually be nicer than during the low season. If you aren’t bothered by a destination’s low-season weather, visiting during the least-busy travel season can save you even more money.

And, if you really need to travel during what is a busy season, aim for flying on the cheaper days of the week: Tuesdays, Wednesdays, and Saturdays. Avoid Fridays and Sundays, which are usually the more expensive days to fly.

Set up fare alert emails

Watching ticket prices fluctuate as you wait for a great deal can be time-consuming, we know. The good news is that you can let technology do the work for you. Several months before your planned trip, you can sign up for fare alerts for the itinerary you want. You’ll get emails when the fare drops, so you can book when the price is right. If your travel plans are flexible, remember that you’ll have to set up a fare alert for each potential itinerary.

How early should I arrive to Denver International Airport International Airport (DEN) before my flight?

The general recommendations for how early to get to the airport are two hours for domestic flights and three hours for international flights. You may be able to adjust that for your specific trip, depending on a few things.

  • How big is the airport? Denver isn’t as gargantuan as some airports we could name, but it’s no tiny regional airport, either. The train connecting the main terminal building to the concourses takes about 10 minutes to reach the C concourse, which is furthest from the terminal.

  • Where is your gate? If your gate happens to be at one end or the other of the concourse, give yourself 5-7 minutes to walk from the airport train to your gate.

  • Do you need to check in at the airport? Airlines have cutoff times for checking in, usually 30-60 minutes before departure, after which you won’t be able to get on the plane. If you’re not able to check in online for any reason, give yourself extra time to check in at the counter.

  • Do you need to check a bag? There’s also a cutoff time for checking bags, usually 45-60 minutes before departure, so allow extra time to check any bags you aren’t carrying on the plane.

  • How busy is the airport going to be? DEN says security waits can be about a half-hour (for standard screening) on average, but that doesn’t take busy travel periods into consideration. If you’re flying around a holiday, the busy summer season, or on a Friday or a Sunday, the wait times at security will be much longer. Not only that, the train to the concourses may be full enough that you have to wait for the next (hopefully emptier) one.

The bottom line is that if you’re traveling light during the off-season and have checked in early, you may be able to get to Denver Airport an hour before your flight (though 1.5-2 hours is going to be the best bet most of the time). During especially busy times, or if you need to check in or check a bag, you may need to arrive 3-4 hours before your flight.
