Delta vs Southwest Airlines: Full Comparison
Assigned seats and global reach vs free bags and flexible fares—how Delta and Southwest really compare.
Where
Delta wins for international routes, premium cabins, and reliability. Southwest wins for free checked bags, simple fares, and flexible changes—your best choice depends on how you travel.
Delta vs Southwest at a Glance
Delta vs Southwest is one of the most interesting matchups in U.S. aviation because the two airlines are built on opposite ideas of what travelers value. Delta is a full-service legacy carrier with assigned seating, premium cabins, and global alliance partners. Southwest is a low-cost carrier with open seating, free checked bags, and ultra-flexible fares.
Neither model is objectively better. The right choice depends on whether you care more about global reach and comfort (Delta) or simple pricing and flexibility (Southwest). This guide breaks down routes, seating, baggage, prices, loyalty programs, and more so you can decide which airline fits your next trip.
You can search both airlines side by side on Travorio, pay with crypto, or spread out your payments with pay-later options.
The Fundamental Difference
Delta assumes travelers want assigned seats, loyalty tiers, premium cabin upgrades, and global connectivity through partners. It’s built as a full-service carrier with multiple cabins and a traditional hub-and-spoke network.
Southwest assumes travelers want low fares, no change fees, and free checked bags. It runs a single-cabin, mostly domestic network with open seating and a simple, no-frills product.
If you value comfort, upgrades, and international options, Delta usually fits better. If you care most about price transparency, flexibility, and baggage savings, Southwest often wins.
Route Networks: Global vs Mostly Domestic
Delta operates major hubs in Atlanta, New York JFK, Los Angeles, Detroit, Seattle, and Salt Lake City. Through its own network and SkyTeam partners, it connects to 300+ destinations worldwide, including Europe, Asia, Africa, and South America.
Southwest runs a point-to-point network focused on the U.S., Mexico, the Caribbean, and a few Central American destinations. It does not fly to Europe, Asia, Africa, or South America and does not belong to a global alliance.
If you’re flying internationally, Delta is usually the only realistic choice between the two. For domestic U.S. trips, Southwest covers most major markets and many secondary cities that Delta may not serve nonstop.
Seating: Assigned Seats vs Open Boarding
Delta uses traditional assigned seating. You pick your seat at booking or during check-in, except on Basic Economy where seat selection is restricted until check-in and often auto-assigned. Main Cabin and above allow seat choice at booking, and higher cabins offer more space and comfort.
Southwest uses open seating with no assigned seats. You receive a boarding position (A, B, or C with a number) based on when you check in or whether you purchased EarlyBird Check-In or a premium fare. You then choose any open seat when you board. Families with young children board between A and B groups.
If you want certainty about sitting together or prefer specific seats (window/aisle, front/back), Delta’s assigned seating is more predictable. If you’re comfortable checking in exactly 24 hours before departure and don’t mind some uncertainty, Southwest’s system can work fine—especially for solo travelers.
Baggage Policy: Southwest’s Big Advantage
Southwest includes two free checked bags for every passenger on every fare. There’s no requirement for status or a co-branded credit card. This is one of the most generous baggage policies in U.S. aviation.
Delta typically charges $35 for the first checked bag and $45 for the second on most domestic routes. These fees are waived for Medallion elites, eligible Delta credit card holders, and passengers in premium cabins.
For a family of four each checking one bag, Southwest can save around $140 one-way compared to Delta if you don’t have status or a qualifying card. For frequent travelers who always check bags, Southwest’s policy can outweigh small fare differences and make it the cheaper option overall.
Fare Flexibility and Change Fees
Southwest charges no change fees on any fare. Wanna Get Away, Wanna Get Away Plus, Anytime, and Business Select tickets can all be changed or canceled; you receive a refund or travel credit depending on fare type. This makes Southwest one of the most flexible major U.S. airlines.
Delta removed change fees on most domestic Main Cabin and above tickets in 2020, but Basic Economy remains non-changeable and non-refundable in most cases. You’ll pay a premium to avoid those restrictions.
If you like to book early and adjust plans later, Southwest is still more forgiving on its cheapest fares. Delta is competitive on flexibility only if you avoid Basic Economy and book Main Cabin or higher.
Inflight Experience and Comfort
Delta offers multiple cabins: Basic Economy, Main Cabin, Comfort+, First Class (on many domestic routes), and Delta One (Business Class) on select long-haul and premium routes. Many aircraft feature seatback entertainment, power outlets, and upgraded snacks and drinks in higher cabins.
Southwest has a single cabin for everyone. Seat pitch is generally comparable to or slightly better than many U.S. carriers’ standard economy, but there are no premium seats, no First Class, and no Business Class. Southwest offers complimentary snacks and non-alcoholic drinks, with Wi‑Fi available for purchase and streaming entertainment via personal devices.
If you want a premium cabin, extra legroom, or an upgrade path using miles or status, Delta is the clear winner. If you just need a straightforward domestic flight and don’t care about premium perks, Southwest’s simple product is usually sufficient.
Loyalty Programs: SkyMiles vs Rapid Rewards
Delta SkyMiles is a revenue-based program where you earn miles based on the price of your ticket and your elite status level. Miles do not expire, and you can redeem them for domestic and international flights, including premium cabins like Delta One. Elite status tiers—Silver, Gold, Platinum, and Diamond Medallion—are earned primarily through Medallion Qualifying Dollars.
Southwest Rapid Rewards is also revenue-based. You earn points based on fare type and ticket cost, and points do not expire. Southwest’s standout feature is the Companion Pass: after earning enough qualifying points or flights in a calendar year, a designated companion can fly with you for only taxes and fees for the rest of that year and the entire following year.
If you value international premium cabin redemptions and alliance partners, SkyMiles is more versatile. If you fly Southwest frequently on domestic routes, the Companion Pass can deliver enormous value and easily beat traditional elite perks in dollar terms.
On-Time Performance and Reliability
Delta consistently ranks near the top among major U.S. airlines for on-time arrivals and overall reliability. Its hub-and-spoke network and strong operational discipline have made it a reliability leader for several years running.
Southwest’s point-to-point network can reduce the risk of cascading delays on some routes, but the airline’s December 2022 operational meltdown exposed weaknesses in its crew scheduling and technology systems. Southwest has since invested heavily in upgrades, but its reputation took a hit.
If on-time performance and reliability are top priorities, Delta generally has the stronger track record over time.
Price Comparison: Which Is Cheaper?
Southwest fares can look higher at first glance, but once you factor in two free checked bags, Southwest often comes out cheaper for travelers who check luggage. A Southwest fare that’s $40 more than Delta’s may still save you money after Delta’s bag fees.
Delta’s Basic Economy can be very competitive for light packers who only bring a carry-on and don’t care about seat selection or flexibility. Main Cabin fares are usually higher than Southwest’s Wanna Get Away fares on similar routes, but they include more flexibility and seat choice.
Always compare the total trip cost—including bags, seat selection, and change flexibility—rather than just the base fare. Travorio’s search tools help you see these trade-offs across airlines.
Which Airline Should You Choose?
Choose Delta if you need international routes, want assigned seating, care about premium cabins or upgrades, or are invested in the SkyMiles ecosystem. It’s especially strong for long-haul trips, business travel, and travelers who value reliability and comfort.
Choose Southwest if you regularly check bags, want maximum flexibility with no change fees, mostly fly domestic or near-international routes, or are working toward the Companion Pass. Families and budget-conscious travelers often find Southwest’s policies more forgiving.
Many frequent travelers use both: Delta for international or premium-heavy trips, and Southwest for domestic journeys where free bags and flexible fares matter more than cabin class.
