#45: United Airlines
United is one of the largest airlines in the United States, based in Chicago, with an extensive global network. It plays a major role in international travel and offers a wide range of routes across every continent.

It ranks here because of the gap between scale and experience. The network is incredibly useful, but the onboard product and service can feel inconsistent. Some flights are perfectly fine, while others fall short, making it harder to rely on for a consistently good experience.
