On January 29, 2026, Morgan Stanley reiterated its Overweight rating on Southwest Airlines and raised its price target by 10% following the carrier’s switch from open boarding to assigned seating. Analysts now project that the new seating model, combined with optional extra-legroom and tiered fare products, will boost annual operating profits by 300%, representing the largest margin expansion in Southwest’s history. Investor reaction was immediate, as shares jumped more than 15% in a single session—their largest one-day gain in 17 years—underscoring confidence in the company’s ability to monetize ancillary services without sacrificing load factors.

During its Q4 2025 earnings call, Southwest reported adjusted EPS that exceeded consensus estimates while noting a revenue shortfall on legacy base fares. Management offset this gap with guidance for 2026 adjusted earnings of at least $4.00 per share, more than triple the prior year’s result and well above the $3.19 analyst consensus. The carrier expects unit revenues to grow at a minimum of 9.5% year-over-year in Q1, driven largely by fees for seat assignments, extra legroom and unbundled in-flight services. The company’s balance sheet remains healthy, with over $3 billion in unrestricted liquidity and a new share-repurchase authorization of $2.6 billion.

CEO Bob Jordan highlighted that the transition to assigned seating represents Southwest’s most significant operational overhaul since adopting its low-cost model in the 1970s. The airline has upgraded its reservation system to support dynamic pricing on new fare classes, expanded its fleet utilization by 4%, and introduced a streamlined boarding process projected to reduce turnaround times by 8 minutes per flight. With a full-year unit cost guidance below industry peer averages and a market capitalization of approximately $25 billion, Southwest is positioned to leverage both volume growth and improved unit yields throughout 2026.
