Frontier has round-trip flights from Dallas (DFW) to Denver (DEN) for $38-$58, NONSTOP. Flights March to May. Departures on Monday, Tuesday, Wednesday, Thursday, and Saturday. Extended weekends available. Origin/Destination reversible.

If you use the Frontier Airlines World Mastercard®, you can avoid bag fees for your first two standard-sized checked-bags. The card has a $99 annual fee, so keep in mind that you’ll need to use the free bag perk at least once a year to break even. Bags normally cost between $49-to-$99 each-way, so if you plan on traveling with bags on Frontier often you can get a lot of potential savings from this perk.

If you don’t have a way to avoid bag fees, consider using a small backpack as your “personal item” when flying Frontier. Dimensions for my Jansport backpack are: 18″ x 13″ x 8.5″. Which is half-an-inch larger than what is officially allowed by Frontier, but it has never been a problem for me. Bag designs like the Jansport SuperBreak backpack (linked) have the same dimensions as the bag I’m using, and also have a large main compartment, which makes it ideal for stuffing as much as you can into the limited amount of space.

Recently starting in 2025, Frontier has made some changes to how they operate bringing them closer in-line to a regular carrier. The first change is adding “first class” seating in the first two rows of their aircraft, the seat size and type is similar to business/first class domestic seating on most regular carriers. The second change is allowing Gold Status and above to get complimentary upgrades into the new “first class” seating. The last major change is that Platinum and Diamond Elite members can get a companion pass for just the tax+fees, which isn’t free, but it avoids the airfare cost of the ticket. There is no limit on the number of times the Companion Travel benefit can be used and the companion can be changed for each flight. This can generate substantial savings if you travel with a partner on Frontier often.

You can usually save more money by booking your flight+hotel together as a package instead of separately.

The Chase Sapphire Preferred® Card allows for 1-to-1 point transfers to several airline loyalty programs. It’s the main travel credit card that we recommend to all our readers. Booking with points is a good alternative to paying with cash when the price of airfare is high. Here is the current list of Chase Sapphire transfer partners: United, Southwest, jetBlue, British Airways, Iberia, Singapore Airlines, Emirates, Air France, KLM, Virgin Atlantic, Aer Lingus, and Air Canada. Instead of just earning and spending points with just one airline you can transfer-points and redeem on any of those airlines.

Do a search on Tripadvisor and GetYourGuide to find guides, tours, attractions, and cool things to do. I use both of those sites to help me plan my own day-to-day itinerary while on vacation.

We post new flight deals often! You can check out our other deals by returning to the Front Page of our website: cheapdfw.com (linked).

Here are some other offers that we think are worth mentioning. List updated 02/21/2025.

We now list coupon codes, discount codes, gift card discounts, and credit card offers that have a better value than their historical averages.

  • Airfare/Hotel coupons on Hopper: (updated daily-ish) Hopper always has discount coupons on their main page. The full list is on Hopper’s website. Keep in mind that Hopper is an OTA, so don’t expect them to honor the free 24-hour cancellation period, or to have the lowest base fare price. Hopper will try to up-sell you on a lot of extras like “cancel for any reason” policies, if you decide to use Hopper we advise that you decline all of those extras.
  • It is common to find Southwest and Alaska Airlines gift-cards for sale at a discount of about -$70 to -$20 off the redeemable value at Costco and Sam’s Club. Before you finalize your booking on either of these airlines, you should check to see if you can save more money by using a gift card.

  • Tips: Use Tripadvisor to create a Hotel “short list”. First, plug in your dates and destination. Then select “Sort by Traveler Ranked”. Finally, select the “Traveler Ranking” filter to show “only 4* and up”. Use this resulting “short list” of hotels to find the cheapest one with a high ranking.
  • Tips: Hotel rates for Weekend dates are usually higher than the rates for Sunday through Thursday. Tripadvisor has a color-coded date calendar, red when the average hotel price for that day is more expensive, green for less expensive. You can use this to get an overview of what dates in the month are at a discount.
  • Tips: Different booking websites will often have differing routes, prices, and availability. Before you finalize your purchase, do a quick check on BookingBuddy, Skyscanner, and Kayak to see if any other site or airline is offering a better deal.
