The Bottom Line Upfront
Southwest Airlines, America's largest domestic carrier, is undergoing a fundamental transformation by abandoning its distinctive practices (open seating, no premium options) in favor of more conventional industry approaches. Despite record revenues of $27.5 billion in 2024, the company faces significant challenges including rising labor costs, Boeing delivery delays, and intense competition. With a strong balance sheet but weakening cost advantages, Southwest aims to achieve 10%+ operating margins by 2027 through network optimization, cost-cutting initiatives, and new revenue streams. Investors are essentially betting on management's ability to execute a complex turnaround in a notoriously challenging industry.
Layer 1: The Business Model 🏛️
The OG Low-Cost Carrier ✈️
Southwest Airlines is essentially the Costco of the skies – a company that built its entire identity around offering a good product at lower prices with exceptional customer service. Founded in 1971 with just three planes flying between three Texas cities, Southwest has grown to become America's largest domestic airline, serving 117 destinations across 42 states and 10 near-international countries with a fleet of 803 Boeing 737 aircraft.
Unlike most major airlines that use a "hub-and-spoke" system (think of a bicycle wheel where all routes connect through central hubs), Southwest primarily uses a "point-to-point" network that offers more direct flights between destinations. It's like taking the highway instead of having to go downtown and transfer to another road every time you want to go somewhere.
How They Make Money 💸
Southwest's revenue comes primarily from four sources:
Passenger Tickets (91% of revenue): Southwest offers four fare types:
Wanna Get Away (basic, non-refundable)
Wanna Get Away Plus (includes transferable flight credits)
Anytime (refundable with priority perks)
Business Select (premium offering with priority boarding and extras)
Ancillary Services (part of "Other" revenue): Things like EarlyBird Check-In (priority boarding), Upgraded Boarding, and pet transportation fees.
Co-Brand Credit Card (majority of "Other" revenue): Their partnership with Chase generates substantial marketing royalties.
Cargo Services (<1% of revenue): Shipping packages and freight.
The Secret Sauce 🥫
Southwest's business model has historically been built on several key ingredients:
Fleet Simplicity: Unlike other airlines that operate 5-10 different aircraft types, Southwest flies only Boeing 737s. This is like having a fleet of identical delivery trucks – same parts, same maintenance procedures, same training for mechanics and pilots. This simplicity reduces costs and complexity.
Secondary Airport Strategy: Southwest often flies into less congested airports (like Chicago Midway instead of O'Hare, or Houston Hobby instead of Bush Intercontinental). These airports typically have lower fees and less traffic, allowing for faster turnaround times.
Customer-Friendly Policies: Southwest doesn't charge for the first two checked bags or for changing flights (though fare differences may apply). These policies have been a major differentiator in an industry notorious for fees.
Rapid Rewards Loyalty Program: Members earn points based on fare amount rather than distance flown, with higher fare types earning more points. These points can be redeemed for any available seat with no blackout dates.
The Times They Are A-Changin' 🔄
In a major strategic shift, Southwest announced in 2024 that it's abandoning some of its most distinctive practices:
Moving from open seating to assigned seats by 2026
Adding premium seating with extra legroom
Forming partnerships with international carriers (starting with Icelandair)
Launching "Getaways by Southwest" vacation packages
Adding overnight "redeye" flights
These changes represent a fundamental pivot as Southwest adapts to evolving customer preferences and competitive pressures. It's like when your favorite indie band finally signs with a major label – purists might be disappointed, but it's probably necessary for survival.
Key Performance Metrics 📊
Southwest measures success through several key metrics:
Load Factor: The percentage of available seats filled with passengers (80.4% in 2024 ↗️)
Revenue Passenger Miles (RPMs): One paying passenger flown one mile (142.5 billion in 2024 ↗️)
Available Seat Miles (ASMs): One seat (empty or full) flown one mile (177.3 billion in 2024 ↗️)
Passenger Revenue per ASM: Revenue divided by available seat miles (14.09 cents in 2024 ↗️)
Cost per ASM (CASM): Operating expenses divided by available seat miles (15.32 cents in 2024 ↗️)
CASM-Ex: CASM excluding fuel and special items (11.95 cents in 2024 ↗️)
Layer 2: Category Position 🏆
The Competitive Landscape 🗺️
Southwest competes in the brutally competitive U.S. airline industry against three main groups:
Southwest has historically occupied a unique middle ground – offering lower fares than legacy carriers but better service and fewer fees than ULCCs. It's like being the Target in an industry of Walmarts and Nordstroms.
Market Position: Domestic Domination, International Hesitation 🇺🇸
Southwest is the largest domestic airline in the U.S. by passengers carried, but unlike its major competitors, it has minimal international presence. While American, Delta, and United earn substantial revenue from lucrative international routes (particularly business-class travel to Europe and Asia), Southwest has limited its international service to nearby destinations in Mexico, the Caribbean, and Central America.
This domestic focus has been both a strength and limitation. During the pandemic, it initially helped Southwest as international travel faced stricter restrictions, but as international premium travel has recovered strongly, Southwest has missed out on this revenue opportunity.
Recent Wins and Challenges 🏆🧩
Wins:
Record operating revenue of $27.5 billion in 2024 ↗️
Successful ratification of contracts with all 12 union-represented workgroups
Fleet modernization progress with 245 fuel-efficient Boeing 737-8 aircraft now in service

The Identity Crisis 🤔
Southwest is currently experiencing something of an identity crisis. The company built its brand on being different from traditional airlines – no assigned seats, no first class, no international connections, no baggage fees. Now it's adopting many industry-standard practices while trying to maintain its customer-friendly reputation.
It's like watching your rebellious friend who swore they'd never "sell out" suddenly put on a suit and join a corporation. Maybe necessary, but definitely a bit jarring.

Growth Drivers and Headwinds 🌬️
Growth Drivers:
Network optimization focusing on more profitable routes
Introduction of assigned seating and premium options to attract new customer segments
International partnerships expanding the network's reach
New "Getaways by Southwest" vacation packages
Overnight "redeye" flights utilizing aircraft during previously idle hours
Headwinds:
Continued pressure on short-haul demand
Intense fare competition in many markets
Boeing delivery delays limiting fleet growth and modernization
Rising labor costs from new union contracts
Lingering reputation damage from the December 2022 operational meltdown
Seasonality Factors 🌞❄️
Like most airlines, Southwest experiences seasonal fluctuations in demand:
Strongest Quarters: Q2 (April-June) and Q3 (July-September), driven by summer vacation travel
Weaker Quarters: Q1 (January-March) and Q4 (October-December), though holiday periods within these quarters can be strong
As the company notes in its 10-K: "In most markets the Company serves, demand for air travel is greater during the summer months, and, therefore, revenues in the airline industry tend to be stronger in the second and third quarters of the year."
Layer 4: Cash Rules Everything Around Me 💰
Margin Trends: Under Pressure 📉
Southwest's profitability metrics have been under significant pressure:
Operating Margin: 1.2% in 2024 (GAAP) ↗️ from 0.9% in 2023, but far below the company's target of ≥10% by 2027
Net Income: $465 million in both 2024 and 2023 (flat)
Return on Invested Capital (ROIC): 2.4% (after-tax) in 2024 ↘️ from 4.0% in 2023, well below the target of ≥15% by 2027
These margins are anemic by Southwest's historical standards and reflect the significant cost pressures the company faces. For context, in the pre-pandemic period, Southwest regularly achieved operating margins in the 16-18% range.
Cost Structure: Labor Pains 👷♀️
Southwest's operating expenses totaled $27.2 billion in 2024, up 5.0% from 2023. The major categories were:
Salaries, Wages, and Benefits: $12.2 billion (45.1% of operating expenses) ↗️
This has increased significantly due to new union contracts
All 12 union-represented workgroups have ratified new agreements since October 2022
Fuel and Oil: $5.8 billion (21.4% of operating expenses) ↘️
Average cost per gallon: $2.64 in 2024 vs. $2.89 in 2023
The company uses fuel hedging to manage price volatility
Maintenance Materials and Repairs: $1.4 billion (5.0% of operating expenses) ↗️
Increasing as the fleet ages, particularly the 737-700 aircraft
Landing Fees and Airport Rentals: $2.0 billion (7.2% of operating expenses) ↗️
Rising due to higher rates charged by airports
Depreciation and Amortization: $1.7 billion (6.1% of operating expenses) ↗️
Increasing due to fleet additions and accelerated depreciation on aircraft planned for early retirement
Southwest's cost advantage has eroded significantly in recent years. The company is targeting more than $500 million in annual cost savings by 2027 through initiatives including minimizing hiring, optimizing scheduling efficiency, and improving corporate overhead.
Balance Sheet: Still Strong 💪
Despite operational challenges, Southwest maintains a strong financial position:
Cash and Short-term Investments: $8.7 billion as of December 31, 2024
Total Debt: $6.7 billion
Unencumbered Assets: Approximately $16 billion, including $13 billion in aircraft value
Credit Ratings: Investment grade from all three major agencies (one of only two U.S. passenger airlines with this distinction)
This strong balance sheet provides Southwest with financial flexibility as it navigates its transformation. The company can fund its initiatives without taking on excessive debt, a luxury many airlines don't have.
Capital Allocation Priorities 📋
Southwest's capital allocation strategy focuses on:
Fleet Modernization: Replacing older 737-700 aircraft with more fuel-efficient 737 MAX models
Added 22 Boeing 737-8 aircraft in 2024
Retired 34 Boeing 737-700 aircraft and 2 Boeing 737-800 aircraft in 2024
Shareholder Returns: $680 million returned to shareholders in 2024
$430 million in dividends
$250 million in share repurchases
Infrastructure Investment: Airport facilities and technology upgrades
New concourse at Los Angeles International Airport (construction expected 2028-2032)
Expansion at Houston Hobby Airport (expected completion 2027)
Fleet Monetization: Sale-leaseback transactions to optimize capital deployment
Completed sale-leaseback of 35 Boeing 737-800 aircraft in December 2024, generating $871 million
The company is trying to balance investing for the future while returning capital to shareholders and maintaining financial strength – a challenging juggling act in the capital-intensive airline industry.
Layer 5: What Do We Have to Believe? 📚
The Bull Case 🐂
For Southwest to succeed, investors need to believe:
Transformation Will Attract New Customers: The shift to assigned seating, premium options, and international partnerships will bring in new customer segments without alienating the existing base. If you've ever avoided Southwest because you hate the boarding process or want extra legroom, you're exactly who they're targeting.
Cost Control Is Achievable: Management can successfully execute on the $500+ million cost savings initiatives to offset labor inflation. This is a tall order but essential for restoring profitability.
Network Optimization Will Improve Yields: Focusing on more profitable routes and reducing unprofitable flying will drive revenue improvements. The company has already begun this process, cutting service to underperforming markets.
Fleet Modernization Will Accelerate: Boeing will resolve production issues, allowing Southwest to replace older aircraft with more efficient models faster. This is largely outside Southwest's control but critical to its cost structure.
Operational Reliability Will Improve: Investments in technology and processes will prevent future meltdowns like the December 2022 event. The company has made this a priority, but the proof will be in the pudding during the next major weather event.
If these factors play out, Southwest could achieve its 2027 targets of 10%+ operating margins and 15%+ ROIC, potentially driving significant share price appreciation from current levels.
The Bear Case 🐻
The key risks to Southwest's outlook include:
Identity Crisis: The move away from distinctive policies could erode brand differentiation without successfully attracting new customer segments. Southwest risks becoming "just another airline" – neither the lowest cost nor the highest quality.
Cost Structure Deterioration: Labor costs and other inflationary pressures could continue to outpace efficiency gains, permanently impairing the low-cost advantage. The new union contracts have locked in higher costs for years to come.
Boeing Dependency Risk: Continued manufacturing problems and certification delays could further disrupt fleet plans and limit growth. Southwest is entirely dependent on Boeing for aircraft.
Competitive Pressure: Legacy carriers with premium offerings and ultra-low-cost carriers with lower cost structures could continue to squeeze Southwest from both directions. It's tough being in the middle.
Management Execution Risk: The significant leadership changes following activist investor pressure create uncertainty about strategic continuity and execution. Many key executives are new to their roles.
Milestones to Monitor 🔍
Investors should watch these key indicators to gauge Southwest's progress:
Assigned Seating Implementation: Scheduled for second half of 2025 (bookings) and first half of 2026 (flights)
Boeing 737-7 Certification and Deliveries: Currently delayed indefinitely
Unit Revenue (RASM) Trends: Need to consistently outpace unit cost growth
Cost Per Available Seat Mile Excluding Fuel (CASM-Ex): Target is low-single-digit growth by end of 2025
Operating Margin Progress: Moving toward the 10%+ target by 2027
International Partnership Expansion: Beyond the initial Icelandair agreement
Final Assessment: Turbulence with Potential Clearing ⛈️➡️☀️
Southwest Airlines stands at a critical inflection point. After decades of success with a distinctive business model, the company is now embracing more conventional industry practices while trying to maintain its customer-friendly ethos. This transformation comes amid significant challenges: rising costs, changing travel patterns, fleet delivery uncertainties, and leadership transitions.
The company's strong balance sheet and brand provide a foundation for this transition, but execution risks are substantial. Success will depend on management's ability to implement complex operational changes while preserving Southwest's cultural strengths and rebuilding its cost advantage.
For investors, Southwest represents a potential turnaround story, but one that requires patience as the transformation initiatives will take years to fully implement and evaluate. The company's 2027 financial targets provide clear benchmarks against which to measure progress, but the path to achieving them remains uncertain in a notoriously challenging industry.
If you're considering an investment in Southwest, you're essentially betting on management's ability to execute a complex transformation in an industry known for thin margins and high fixed costs. It's not for the faint of heart, but if successful, the upside could be substantial from current levels.
As the airline itself might say: You are now free to move about the investment cabin – just keep your seatbelt fastened for turbulence.
