LUV vs NWN: Which Is the Better Buy in 2026?

Same yardstick, side by side (as of August 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

Reading it: LUV is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. LUV and NWN share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined LUV and NWN exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

Southwest Airlines operates a point-to-point domestic US network built around a single fleet type, the Boeing 737, which historically kept training, maintenance, and scheduling costs low. For more than five decades the carrier ran on open seating, two free checked bags, and a no-frills brand that made it the archetype of the American low-cost airline. That model is now being dismantled: in 2025 Southwest introduced checked-bag fees (roughly $35 for the first bag and $45 for the second) and basic-economy-style fares, and on January 27, 2026 it ended open seating and began selling assigned and extra-legroom premium seats.

The group also owns the Mist underground gas storage facility in Oregon, which is partly FERC-regulated and sells interstate storage services. Together the businesses reach nearly one million customers in seven states, and the company has operated for more than 167 years.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• LUV drivers: Product monetization and premium mix; Cost discipline and CASM.
• NWN drivers: SiEnergy and Texas customer growth; Rate cases converting capital spending into revenue.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: Southwest remains almost entirely exposed to US domestic leisure and business demand, so any economic softening or pullback in travel hits revenue directly. For NWN, decarbonization policy is the structural risk that separates NWN from a Sun Belt gas utility: Oregon and Washington both pursue aggressive emissions reduction from building gas use, and electrification mandates, building-code changes or new compliance costs could shrink the customer base the rate base is spread across.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick LUV if you believe its drivers more; NWN if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the LUV and NWN guides.

LUV. Southwest returned to profitability in Q1 2026 on record first-quarter revenue, reversing a year-ago loss as new product initiatives lifted unit revenue by double digits. Management reiterated a roughly $4.00 full-year adjusted EPS target and guided Q2 RASM up meaningfully year over year. The P/E near 33x on trailing earnings reflects a stock priced on the expectation that the margin recovery continues rather than on current earnings alone.

NWN. Valuation sits in the normal band for a small-cap regulated gas utility, at roughly 17 times trailing earnings and around 16 times the midpoint of 2026 guidance of $2.95 to $3.15 per share, which management now expects to land in the upper half. Reported figures are all in US dollars. Because earnings are concentrated in the heating season, quarterly comparisons are close to meaningless in isolation: the June 2026 quarter produced ~$0.01 per share and the first half produced ~$2.33, so the trailing twelve-month number is the only fair basis for a multiple.

Headline figures (approximate, APRIL 2026): LUV shows revenue (q1 2026) ~$7.25B, revenue (ttm) ~$27B, net income (q1 2026) ~$227M, diluted eps (q1 2026) ~$0.45; NWN shows revenue (ttm) ~$1.29B, net income (ttm) ~$126M, diluted eps (ttm) ~$2.99, market cap ~$2.1B.

LUV and NWN are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme. Walnut can show your combined LUV and NWN exposure against your real portfolio. It is not an investment adviser.
