Southwest Airlines Flights from Dallas to Cancun

Southwest Airlines on this route

Dallas is a Southwest Airlines hub, so Southwest Airlines typically offers several daily departures on DFW–CUN, with nonstop service where demand supports it and connections through its other hubs otherwise. The nonstop flight time is about 2h 44m.

Fare classes available: Basic, Choice / Choice Preferred, Choice Extra. Southwest does not charge change fees on any fare; you pay the fare difference if the new flight is more expensive.

Recorded lows on DFW–CUN start at $174 one-way. That figure comes from cached search data and moves with demand, so treat it as a benchmark for what a good price looks like rather than a guaranteed fare.

Delta Air Lines and United Airlines both operate hubs at one end of this route, so nonstop or single-connection service is usually available, along with American Airlines and Southwest Airlines. Our agents can book any of them and compare fare classes side by side.

Expect roughly 2h 44m nonstop for the 1,030 miles. On routes this length, basic economy and standard economy often differ by less than a checked-bag fee, so it pays to price the higher fare with the bag included.

When to fly

For long-haul travel, mid-January to March and the shoulder months of October and November usually bring the lowest fares; June through August and the December holidays cost the most.

On this specific route our fare history shows February as the cheapest month and June as the most expensive, a spread of $224 between the two.

Midweek travel almost always beats weekends on price here. If your dates are flexible by a day or two, tell the agent; shifting a Friday departure to Thursday or a Sunday return to Monday is the single most reliable way to cut the fare.

For international travel, booking two to five months ahead usually gets the best fares; inside three weeks, prices rise sharply. Peak-season travel in summer and over the December holidays should be booked as early as possible.
