Southwest Airlines (LUV) Q3 2026 earnings review
Southwest ticket revenue jumps, but fuel costs cut profit plans
Southwest Airlines proved customers will pay its new seat and bag fees, but higher fuel prices ate the gain. Revenue per seat mile jumped 22% from a year ago, beating the company's plan even after passing the one-year mark of charging for checked bags. Chief executive Bob Jordan said the new earnings power is durable, yet a 63% rise in fuel prices held third-quarter profit per share excluding one-offs to $0.66.
| Unit revenue (RASM) | +21.6% from a year ago (plan: 17.5% to 19.5%) |
|---|---|
| Profit per share, excluding one-offs | $0.66 $0.11 a year ago |
| Jet fuel cost per gallon | $3.92 +63% from a year ago ($4.55 planned for Q4) |
| Full-year profit per share outlook | Cut 27% to $2.60–$2.85 (from $3.25–$4.25) |
⚖️ Verdict: ⚪ Neutral
The story is unchanged because commercial progress and fuel costs moved equally in opposite directions. Unit revenue stayed near 20% in the third quarter and the fourth-quarter outlook, easing fears of a slowdown after the bag-fee anniversary. The bad news: because the airline ended its fuel hedging programme last year, fuel at $4.55 a gallon forced management to cut the full-year profit plan by 27% by our math, while $214 million in aircraft sales masked rising operating costs.
The question now is whether higher ticket prices are coming at the expense of customer traffic and underlying cost control. Optimists see a richer mix of business travellers and fee revenue; sceptics point to a 3% drop in passengers carried and heavy reliance on plane sales to hit cost targets. Fourth-quarter passenger counts as seating capacity expands will tell.
🐂 Bull Case
Unit Revenue Accelerated Past the Bag-Fee Comparison
Investors worried that revenue growth would slow once Southwest Airlines passed the one-year mark of charging for checked bags, which started in May 2025. Chief executive Bob Jordan said results passed that test: "Demand remained strong as we lapped last year's bag fee and other commercial initiatives, reinforcing our belief that the earnings power we've built is durable, even with significantly higher fuel costs."
Instead of slowing down, unit revenue (RASM, or revenue for each seat flown a mile) grew faster than in the second quarter. The US carrier also kept total seating capacity tight after closing stations in Chicago O'Hare and Washington Dulles earlier this year.
- Third-quarter unit revenue: 18.55 cents, up 21.6% from a year ago and above the 17.5% to 19.5% plan
- Fourth-quarter unit revenue outlook: up 19% to 21% from a year ago
- Third-quarter seating capacity: down 0.4% from a year ago
The third-quarter result and the fourth-quarter outlook together ease the concern about the bag-fee comparison, because unit revenue is holding near 20% growth across two consecutive quarters after the anniversary. Assigned and extra-legroom seating, which launched in January 2026, is now carrying the top line.
What to watch: the first-quarter 2027 unit revenue outlook, arriving in January. That quarter marks one full year since assigned seating launched, so it will show whether ticket prices can keep rising without a new fee.
Corporate Bookings and Loyalty Perks Expand
Southwest wants more business travellers and credit-card users to fill its planes at higher fares. Corporate travel hit a third-quarter record, with "20 of the 50 all-time top managed business booking days occurring during the quarter", the airline said. It also added New Distribution Capability (NDC), a booking technology that lets corporate travel agencies see and buy its upgraded fares.
To keep frequent flyers spending, the Dallas-based carrier revamped its Rapid Rewards loyalty programme, adding a new Platinum tier and "a faster path to status through card spend". Still, Other operating revenue — where the marketing portion of credit-card fees sits — rose only 4.5% from a year ago to $621 million, lagging the 22.8% jump in passenger ticket and fee revenue.
What to watch: the loyalty revenue breakdown in the third-quarter Form 10-Q filing. A pickup in loyalty revenue growth above the second quarter's 7.8% pace would show that recent card sign-ups are turning into cash for the airline.
🐻 Bear Case
Unhedged Fuel Costs Cut the Full-Year Profit Plan
Southwest ended its fuel hedging programme in 2025, leaving its profit exposed when oil prices rise. In the third quarter, jet fuel cost $3.92 per gallon, up 63.3% from $2.40 a year ago and above the $3.70 to $3.75 management planned for in July. That added $821 million to operating expenses and took $1.08 off profit per share, the company said.
- Fuel expense as a share of revenue: 25.6%, up 6.4 percentage points from a year ago by our math
- Fourth-quarter fuel price assumption: $4.55 per gallon, up from $3.92 in the third quarter
- Full-year profit per share outlook, excluding one-offs: cut to $2.60–$2.85 from $3.25–$4.25
Even with fuel taking a larger share of sales, operating margin excluding one-offs rose 4.8 percentage points to 5.4%. That happened because revenue grew faster than staff pay and benefits (down 4.3 percentage points of revenue by our math) and overhead costs (down 4.0 points). But the fourth-quarter fuel jump to $4.55 per gallon forced management to cut the full-year profit outlook by 27% at the middle of the range.
What to watch: jet fuel market prices relative to the $4.55 per gallon fourth-quarter assumption. Any further rise in fuel prices will cut fourth-quarter profit directly because the carrier has no active hedges.
Aircraft Sales Masked Rising Operating Costs
Southwest measures its cost control using non-fuel unit cost (CASM-X, the cost to fly a seat one mile excluding fuel, one-offs, and profit sharing). Reported non-fuel unit cost rose 3.8% from a year ago, landing inside the 3.5% to 4.0% outlook. Management plans for 4.0% to 4.5% growth in the fourth quarter, which includes a 1-point penalty from "the removal of six seats from the Boeing 737-700 fleet to enable extra legroom seating".
However, the carrier credits gains from selling planes against its operating expenses. In the third quarter, it booked a $214 million gain — $96 million from "retiring aircraft and engine sales" and $118 million from selling planes and leasing them back — compared with $13 million a year ago. By our math, without those fleet gains in both periods, non-fuel unit costs rose 7.4% rather than 3.8%.
Relying on aircraft sales to hold down reported costs matters because fleet gains are not ongoing ticket operations. Meanwhile, return on invested capital after tax over the past twelve months reached 11.3%, still short of the 15% target set for 2027.
What to watch: fourth-quarter gains on asset sales and sale-leasebacks in the cash flow statement. A drop in plane sales would expose the higher underlying growth in staff and airport costs.
Higher Fares Are Pushing Some Flyers Away
Jordan said customers are responding well to the new product offerings. The revenue numbers agree, but passenger counts show a trade-off between ticket prices and traffic.
In the third quarter, the average passenger fare jumped 26.9% from a year ago to $231.69. Over the same three months, revenue passengers carried fell 3.2% to 33.5 million, even though available seat miles dipped only 0.4%. Load factor — the share of seats filled — stayed flat at 79.8% only because the remaining passengers flew 2.9% longer distances on average.
What to watch: fourth-quarter revenue passengers carried as seating capacity expands 3% to 4% from a year ago. If passenger counts keep falling while the airline adds seats, it will have to discount fares to keep planes full.
Risks this quarter didn't answer
Four standing concerns cannot be checked from the earnings release alone because the detailed tables live in the quarterly filing or prepared remarks.
- Ancillary fee revenue (bags and seat assignments sold separately): not in the release; Note 5 of the Form 10-Q filing will show whether it held its $875 million second-quarter level.
- Air traffic liability (cash from advance bookings and loyalty points): rose 1.9% from a year ago to $8.28 billion by our math, trailing the 21.2% revenue rise; the Form 10-Q will split travel bookings from loyalty points.
- Starlink WiFi roll-out: the release notes fleet-wide completion by fall 2027, but gives no count against the goal of 300 planes by year-end 2026.
- Boeing 737-7 certification: full-year deliveries rose to 67 planes from 64, but the release gives no certification date for the smaller 737-7 model.

First Airport Lounges and March Investor Day
Southwest is adding perks common at legacy airlines. It announced the Southwest Icon Lounge network, "the Company's first airport lounges, with the first guests expected in 2027", alongside flight shopping inside ChatGPT and partnerships with TAP Air Portugal and LOT Polish Airlines. Jordan will present multi-year financial targets at a Capital Markets Day in New York on March 2, 2027.
💲 Other KPIs
Total debt (short-term and long-term borrowings) rose 43.5% from a year ago by our math, up from $4,102 million after the company borrowed $1.5 billion earlier in 2026. As a result, quarterly interest expense doubled from a year ago to $70 million. Southwest bought back no shares in the third quarter, leaving $450 million on its repurchase plan.
Cash flow remained negative in the quarter by our math, as $1,006 million in capital spending for aircraft and technology exceeded $513 million in operating cash flow. The cash outflow widened by $45 million from a year ago. Proceeds of $497 million from selling and leasing back aircraft covered the gap and funded $176 million in dividends.
🔮 Guidance
Cut. The middle of the full-year profit range dropped by $1.03 per share, or 27% by our math, after already stepping down last quarter from an initial floor of at least $4.00. Higher jet fuel costs drove the reduction. With $2.05 per share earned in the first nine months, the full-year plan matches the new fourth-quarter outlook.
Cut against what the prior full-year plan implied. The middle of the fourth-quarter range ($0.68) is up 16% from $0.58 a year ago by our math, but sits 61% below the $1.11 to $2.36 range that last quarter's full-year target required. The forecast assumes jet fuel rises to $4.55 per gallon.
New. The plan calls for 20% unit revenue growth at the middle of the range, slightly below the third quarter's 21.6% pace. Combined with the 3% to 4% seating capacity expansion, the forecast points to fourth-quarter total revenue growth of about 24% from a year ago by our math.
New. Non-fuel unit cost growth steps up from 3.8% in the third quarter to 4.25% at the middle of the fourth-quarter range. That includes a 1.0 percentage point penalty from removing six seats per plane on the Boeing 737-700 fleet to make room for extra-legroom rows.
Trimmed. Fourth-quarter seating capacity will grow 3.5% at the middle of the range, slightly below the roughly 4.5% increase discussed on last quarter's call, but a sharp step-up from the 0.4% contraction in the third quarter.
Cut. It is the third consecutive reduction to the full-year seating plan, stepping down from 2%–3% at the start of the year: -0.5 points, -0.5 points, and -0.3 points.
Cut. Net capital spending — which subtracts cash received from aircraft sales and sale-leasebacks — drops by $625 million at the middle of the range, helped by $947 million in asset sale proceeds collected across the first nine months.
Raised on deliveries, unchanged on retirements. Expected Boeing deliveries rose by three aircraft to 67, while planned retirements stay at roughly 60 planes.
❓ Key Questions
How much did ancillary fees contribute in Q3?
Fees for bags and seat selection reached $875 million in the second quarter. Since the earnings release only gives total passenger revenue, investors need the Form 10-Q breakdown to see whether fee revenue grew from last quarter.
What are the cost and return targets for Airport Lounges?
Building the new Southwest Icon Lounge network requires airport real estate and ongoing operating spend. Management has not yet sized the capital bill or said whether its previous 2027 goals of 15% return on capital and 10% operating margin still stand.
Why is advance booking cash still lagging revenue growth?
Total air traffic liability — cash held for future flights and loyalty points — rose just 1.9% from a year ago by our math, while revenue jumped 21.2%. Without the split between ticket bookings and loyalty points, the gap remains unexplained.
How much of Q4 cost control relies on plane sales?
Gains from selling and leasing back aircraft lowered third-quarter operating costs by $214 million, or 3.6 percentage points of non-fuel unit cost growth by our math. Management has not disclosed how many aircraft sales are baked into the fourth-quarter cost outlook.
