What We Found: Observed Fares from Dallas-Area Airports to Denver

The greenspicks editorial team searched 2 route combinations on June 20, 2026, and both returned cached fare data from Travelpayouts. These are individual observations tied to specific travel dates, not a controlled comparison or comprehensive market survey.

Here is exactly what the data showed:

From DFW (Dallas/Fort Worth International):

  • $71 one-way on Frontier, nonstop, 133-minute duration, departing July 4, 2026
  • $133 one-way on Frontier, nonstop, 130-minute duration, departing July 6, 2026

From DAL (Dallas Love Field):

  • $110 one-way on Southwest, nonstop, 120-minute duration, departing July 4, 2026
  • $177 one-way on Southwest, nonstop, 135-minute duration, departing July 6, 2026

Key finding:

These are individual cached observations across different dates, not a controlled comparison. The $62 difference between the lowest ($71) and second-lowest ($133) fare came from different travel dates, not airline pricing differences.

All fares listed are one-way. Roundtrip pricing was not included in this data pull.

DFW vs DAL: Which Dallas Airport for Denver Flights?

Both Dallas-area airports showed fares to Denver International Airport (DEN) in observed data. The choice between them affects which airlines you can fly and potentially what you pay.

DFW (Dallas/Fort Worth International) showed Frontier service in the observed fares. This is the larger airport with more total flight options across carriers.

DAL (Dallas Love Field) showed Southwest service. Love Field is closer to downtown Dallas and generally smaller, which some travelers prefer for shorter security lines.

The greenspicks team did not pull parking costs, taxi fares, rideshare estimates, or public transit costs for either airport. These vary significantly based on where you live in the Dallas metro area. Verify current airport access costs independently before factoring them into your total trip budget.

The practical takeaway: search both airports for your travel dates. One may offer significantly better pricing or timing depending on when you fly.

How to Find Cheap Dallas to Denver Airfare: Step-by-Step

Observed fares ranged from $71 to $177 one-way across four data points. That variation illustrates why a systematic search approach matters more than hoping you land on the right date.

  1. 1

    Check both DFW and DAL as origin airports

    Run separate searches from Dallas/Fort Worth International and Dallas Love Field. Different airlines serve each airport, and fares can vary substantially between them for the same travel date.

  2. 2

    Use flexible date search tools

    Most flight search engines let you view fares across a range of dates. Use calendar views or flexible date features to spot lower-priced days. For more on this approach, see our guide to finding flight deals with flexible date searches.

  3. 3

    Compare multiple booking sources

    Aggregators, airline websites, and online travel agencies sometimes show different prices for identical flights. Check at least two or three sources before booking.

  4. 4

    Set fare alerts for the route

    If your travel dates are flexible, set up price alerts through Google Flights, Hopper, or similar flight price tracker tools. You will get notified when fares drop for your route.

  5. 5

    Consider day-of-week flexibility

    Fares often vary by departure day. If you can shift your trip by a day or two, you may find lower prices. Our observed data showed a $62 difference between July 4 and July 6 on the same airline from DFW. Review our analysis on cheapest days to fly for general patterns.

  6. 6

    Review airline-direct pricing alongside aggregators

    After finding a fare on an aggregator, check the airline’s own website. Some carriers offer price matching or slightly lower fares when you book direct, and you may have more flexibility with changes or cancellations.

Airlines Flying Dallas to Denver: What the Data Showed

Two airlines appeared in the observed fares: Frontier and Southwest. Each operates from a different Dallas-area airport.

Frontier (F9) appeared in fares from DFW to DEN:

Southwest (WN) appeared in fares from DAL to DEN:

Baggage fees, seat selection fees, and carry-on policies were not included in this data pull. Verify current fee structures on each airline’s official website before booking, as these costs can significantly change the total price you pay.
