Timing note: Today is Wednesday, July 22, 2026. The prompt describes the report as “tomorrow” but also lists July 22, 2026; those dates conflict. This preview therefore treats the 2Q26 release as imminent.
Southwest enters 2Q26 with a much different earnings setup than a year ago. The company’s assigned seating, extra-legroom products, bag fees, revised fare architecture, and revenue-management changes are now fully in market. In 1Q26, that translated into an 11.2% year-over-year RASM increase, a 4.6% operating margin, and $0.45 of EPS, despite a roughly $0.22-per-share fuel headwind versus its prior fuel assumption.
For 2Q26, management guided to:
| Metric | 2Q26 guidance |
|---|---|
| Adjusted EPS | $0.35–$0.65 |
| Capacity / ASMs | Flat to +1% YoY |
| RASM | +16.5% to +18.5% YoY |
| CASM-X | +3.5% to +4.0% YoY |
| Fuel cost | $4.10–$4.15/gallon |
The headline is straightforward: revenue momentum should be exceptional, but fuel is absorbing a meaningful portion of the benefit. The market will likely care less about whether LUV lands at the midpoint of EPS guidance than whether its commercial initiatives are proving durable enough to sustain margin expansion through the second half.
The key report-card item is unit revenue. Southwest’s +16.5% to +18.5% 2Q RASM outlook is dramatically above its 2Q25 result, when RASM fell 3.1% on capacity growth of 1.6%.
That guidance implies a very large revenue step-up. Using 2Q25 operating revenue of $7.24 billion as a base, the company’s RASM and capacity outlook broadly points to approximately $8.4 billion–$8.7 billion in 2Q26 operating revenue, before any rounding or mix effects.
The more important question is quality and composition:
Management said in April that at least half of its 1Q yield increase was attributable to customers voluntarily purchasing up into higher products. It also reported that roughly 60% of customers upgraded from the base product, versus approximately 20% in 2025. Confirmation that this behavior persisted through the peak summer period would be the most important fundamental positive.
Southwest discontinued its fuel-hedging program in 2025. That makes quarterly earnings more directly exposed to jet-fuel moves than in the past.
The contrast is stark:
The company indicated in April that elevated fuel was the principal factor preventing it from reaffirming its full-year $4.00 adjusted EPS objective with greater confidence. Management’s message was effectively: the transformation is performing at or somewhat ahead of plan, but the path to $4 depends on fuel and revenue trends.
For investors, the important items are:
A beat caused solely by lower-than-assumed fuel would be less valuable than a beat driven by incremental RASM or lower CASM-X.
The 2Q release should offer the clearest evidence yet on whether Southwest’s strategic reset is creating a structurally higher-margin airline rather than simply benefiting from a favorable pricing environment.
The proof points to watch include:
Management has been explicit that it is prioritizing RASM and margins over market share or full aircraft. That means a modestly lower load factor should not automatically be viewed negatively if it accompanies materially stronger yield and unit revenue.
Southwest guided 2Q CASM-X up 3.5%–4.0%, including a roughly 1.2-point headwind from removing six seats from 737-700 aircraft to create extra-legroom capacity.
That is a reasonable cost outcome given low capacity growth, but investors should focus on the underlying run rate. In 1Q, CASM-X rose just 2.3%, better than expected, helped by operational efficiency, technology spending discipline, maintenance optimization, and a fleet shift toward newer 737-8 aircraft.
A favorable 2Q cost outcome would reinforce management’s claim that its improvement is structural. Conversely, CASM-X above guidance would raise concerns that low growth and product complexity are diluting the operating leverage from higher revenue.
The biggest call question will likely be the status of the $4.00 full-year adjusted EPS target. Management did not withdraw that target in April, but said hitting it would require lower fuel and/or stronger revenue performance.
A constructive outcome would be:
Balance-sheet flexibility remains a relative strength. At March 31, Southwest had $3.3 billion of cash, a $1.5 billion revolver, leverage of 2.2x adjusted debt to adjusted EBITDAR, and approximately $16.5 billion of unencumbered aircraft and related assets. It also repurchased $1.25 billion of stock in 1Q, leaving $450 million under its authorization. The potential tension is clear: continued buybacks are attractive if cash generation remains strong, but elevated fuel, capital spending, and fleet investment argue for maintaining balance-sheet guardrails.
LUV closed at approximately $48.70 on July 21, up about 29% since the day after its 1Q26 earnings release, though about 6.5% below its June 25 closing high of $52.09. That suggests investors have already assigned meaningful value to the turnaround and improved domestic-airline pricing environment.
As a result, the bar is likely higher than simply reporting an in-range quarter. Investors will want confirmation that:
This is primarily a quality-of-earnings and trajectory report. The quarter should show a dramatic year-over-year improvement in revenue and margin versus 2Q25, when Southwest earned $0.43 on an adjusted basis and struggled with weak unit revenue. But the decisive issue is whether the company can demonstrate that its new commercial model is producing enough recurring RASM and margin lift to offset a far less favorable fuel backdrop.
A strong report would pair an upper-half EPS result with evidence that buy-up, corporate demand, premium seating, and ancillary revenue are still improving. A merely in-line result with cautious full-year commentary could disappoint, because the stock’s recovery implies that investors are increasingly expecting the transformation to work.
