United Airlines Holdings, Inc. is benefitting from buoyant air-travel demand, reflected in a significant year-over-year increase in revenue for Q4 2022 driven by a 62.9% rise in passenger revenues. The airline transported nearly 39 million passengers in the quarter, and management expects revenue per available seat mile to grow in the 22-23% range for Q1 2023. United Airlines’ focus on its cargo operations is partly offsetting weakness in passenger revenues from 2019, with cargo revenues jumping 42.5% year-over-year in 2021 and 84.1% from the 2019 level in 2022. However, the current ratio has decreased, indicating a decline in United Airlines’ ability to generate cash. The airline currently carries a Zacks Rank #3 (Hold). Better-ranked stocks in the Zacks Transportation sector are American Airlines and Alaska Air Group, benefiting from improved air-travel demand.
