United Airlines is undeniably on a quest to become the nation’s largest and most profitable airline, and it undoubtedly has its sights set on taking down Delta Air Lines, which has historically held this position. With the carrier’s financial performance in 2024 being one of the best years on record, the airline is flush with cash and prepared to make investments across its network. Not only is the airline launching new routes in key international markets, but it is also looking to expand its presence in some of the US’s most important domestic travel markets.
