Routes and Destinations: Delta Takes the Lead
Winner: Delta Air Lines
When it comes to sheer reach, Delta clearly outperforms Southwest.
Southwest Airlines Network
Southwest primarily serves North America, covering over 115 airports across the U.S., Mexico, Central America, and the Caribbean. Its point-to-point route model allows for many nonstop flights between mid-sized cities, which can be extremely convenient for domestic travelers.
For example, Southwest often offers nonstop routes between city pairs that other airlines serve only through hubs. This makes it attractive for travelers who want fewer connections within the U.S.
Southwest has also announced partnerships with international airlines like Icelandair and China Airlines, which will eventually allow combined itineraries—but these partnerships are still limited compared to global alliances.
Delta Air Lines Network
Delta operates flights to nearly 300 destinations across six continents. As a core member of the SkyTeam alliance, Delta passengers gain access to over 1,000 destinations worldwide through partner airlines such as Air France, KLM, Virgin Atlantic, and Korean Air.
If international travel—or flexibility across continents—is important to you, Delta is the stronger option by a wide margin.

Basic Economy and Fare Flexibility: Southwest Has the Edge
Winner: Southwest Airlines
Both airlines offer restrictive entry-level fares, but Southwest’s basic option is more forgiving.
Southwest’s lowest fares still allow cancellations for flight credit (though credits expire), and passengers earn some reward points. Delta’s Basic Economy fares are more restrictive, often excluding seat selection, mileage earning, and flexibility unless you pay a cancellation fee.
For travelers who want flexibility even on cheaper tickets, Southwest is the better choice.
Premium and First-Class Experience: Delta Dominates
Winner: Delta Air Lines
Delta is far superior in premium travel.
- True first class and business class cabins
- Premium economy options
- Consistently high customer satisfaction ratings
- Over 50 Delta Sky Club airport lounges
Southwest does not offer first class, business class, or airport lounges. While it does sell seats with extra legroom, the experience does not compare to Delta’s premium offerings.
If comfort, upgrades, and lounges matter to you, Delta is the clear winner.

Loyalty Programs: A Strategic Tie
Winner: Tie (Depends on Travel Style)

Credit Card Options: Delta Offers More Variety
Winner: Delta Air Lines
Delta provides a wider range of co-branded credit cards through American Express, including multiple personal and business options at different annual fee levels. Higher-tier cards include lounge access, free checked bags, priority boarding, and upgrade eligibility.
Southwest’s credit cards, issued by Chase, are fewer but still valuable—especially for frequent Southwest flyers who benefit from boarding perks and bonus points.
