United Airlines Holdings (UAL) recently saw a 24.7% increase in its share price over the last quarter. This upward movement coincided with important developments, such as the completion of the DOT review for its collaboration with JetBlue Airways, which opens avenues for enhanced customer benefits and operational synergies. Meanwhile, UAL's buyback program, where over 3.5 million shares were reacquired, may have bolstered investor confidence. Although the company's Q2 earnings revealed a decrease in net income, the revenue still saw a modest increase. These factors likely played a role, although the overall market rally would have been a key influence as well.
