Boeing Glitch Tests United Airlines Holdings Amid Undervalued Narrative

United Airlines Holdings (UAL) is facing scrutiny over a Boeing software glitch affecting some 737 MAX jets, even though none of its operating 737s use the affected version. Despite this setback, the carrier's share price has retreated 18% in the past 90 days and slipped 2.2% to about $111.51 on the day.

The airline's financial results have been solid, but it still carries the scars of a turbulent sector. Analysts believe that executing its United Next fleet modernization strategy could unlock further operational leverage and drive operating margin improvement over the next several years.

However, there are risks to this narrative, including higher financial leverage during a downturn or congestion and reliability issues at key hubs persisting and eroding premium customer demand. The airline's story is seen as undervalued by 31% of investors, with a fair value estimate of $162.15 against the recent close of $111.51.
