Financial Performance:
Southwest reported Q4 EBIT of $386 million and full-year EBIT of $574 million (above $500M guidance). Q4 operating revenue reached record $7.4 billion with full-year record $28 billion (up 1.7% YoY). Q4 RASM declined 0.2% YoY, impacted by FAA-mandated schedule cuts during government shutdown. Full-year adjusted EPS: $0.93.

Transformation Milestones:
CEO Bob Jordan called 2025 “a year of meaningful transformation,” implementing unprecedented changes: bag fees, basic economy fare, flight credit expiration, Rapid Rewards program optimization (variable earn/burn rates), amended Chase co-brand agreement, free WiFi for loyalty members (T-Mobile partnership), OTA distribution (Expedia, Priceline), 6 new airline partners, Getaways by Southwest, redeye flying, reduced turn times, discontinued fuel hedging, and $2.6 billion share buybacks (14% of shares outstanding).

Major Product Launch:
January 28, 2026: Implemented assigned seating and extra legroom across entire fleet after retrofitting 800+ aircraft. All conversions, technology development, and employee training completed on schedule. Operated 3,200+ flights flawlessly on launch day while maintaining industry-leading reliability.

2026 Guidance:
Full-year adjusted EPS: at least $4 (materially higher than 2025’s $0.93), representing lower end of internal forecast. Q1 adjusted EPS: at least $0.45 (vs. -$0.13 loss in Q1 2025). Q1 RASM expected up at least 9.5% YoY driven by yield, load factor, initiatives, and loyalty programs. Management withholding upper range guidance pending 1-2 months of close-in booking data, particularly business traveler ancillary uptake rates.

Fleet & Aircraft:

Q4 2025:
- Received 19 Boeing 737-8 aircraft
- Retired 18 aircraft: 14 Boeing 737-700s, 4 Boeing 737-800s (sold)
- Ending fleet: 803 aircraft (flat YoY)

Full-Year 2025:
- Received 55 Boeing 737-8 deliveries
- Retired 55 aircraft: 48 Boeing 737-700s, 7 Boeing 737-800s (5 sold)
- Net fleet growth: 0 aircraft

2026 Plans:
- Expected deliveries: 66 Boeing 737-8 aircraft
- Planned retirements: ~60 aircraft
- Net fleet growth: ~6 aircraft
- CapEx: $3.0-3.5 billion (net, including aircraft sales proceeds)

Aircraft Modifications:
- Retrofitted 800+ aircraft for assigned/extra legroom seating
- Removed 6 seats from 737-700 fleet to enable extra legroom (1.1 point Q1 CASM-X impact)
- Delayed some 737-700 retrofits from December to January to maximize holiday revenue while minimizing costs

Capacity & Utilization:
- Q4 capacity: +5.8% YoY despite flat fleet count (efficiency gains: reduced turn times, redeye flying)
- Full-year 2025 capacity: +1.6% YoY
- Q1 2026 capacity: +1% to +2% YoY with ~7 fewer aircraft (continued efficiency improvements)

Cost Performance:
Q4 CASM-X: +0.8% YoY (beat guidance). Exceeded $370M cost reduction target for 2025, including first-ever layoff of non-contract/management employees. Q1 2026 CASM-X: +~3.5% YoY (includes 1.1 points from 737-700 seat removal). Management headcount expense flat to 2025 levels in 2026. Pursuing additional cost takeout and efficiency beyond 2025 achievements.

Balance Sheet & Capital Allocation:
Ended Q4 with $3.2 billion cash and 2.4x gross leverage ratio. Issued $1.5 billion unsecured bonds in November at industry-leading terms. 2025 shareholder returns: $2.6 billion buybacks + $399M dividends while maintaining investment-grade rating. Net debt reduction $492M in 2025 (10% decrease).

Operational Excellence:
Ranked #1 in Wall Street Journal’s Best U.S. Airline 2025. December: #1 on-time performance, #1 completion factor, lowest extreme delays industry-wide. Achieved record operational reliability despite historic winter storm and largest-ever same-day product transformation.

Revenue Initiatives Performance:
Early results from assigned seating/extra legroom “overwhelmingly positive.” Customer buy-up behavior exceeding expectations. Ceased selling Early Bird for post-January 27 departures; replaced with seat selection ancillaries. Expect shift from 80%+ buying lowest fare to ~50% or less buying basic economy. Close-in bookings (business travelers) showing higher ancillary uptake—key driver of potential guidance upside.

Corporate Travel:
Q4 corporate bookings: up mid-single digits (excluding volatile government segment). January 2026: “very strong start” with high corporate bookings. Invested in corporate infrastructure (sales force, BTN #2 ranking behind Delta, OTA distribution). New product expected to drive incremental corporate share as travelers can now expense premium seats/services.

Strategic Outlook:
Management emphasized “no victory lap”—transformation continuing with network optimization, further cost reduction, corporate share growth. Pursuing additional upside beyond current initiatives through capacity reallocation within existing footprint rather than aggressive expansion.
