American Airlines, United Airlines, and Delta Air Lines are companies that let people fly in airplanes to different places. Today, some people who own parts of these companies (called shares) are selling them because they think the companies might not make as much money as they thought. This makes the prices of the shares go down. American Airlines is not doing as well as United Airlines and Delta Air Lines recently, so its shares are also going down more. The boss of American Airlines wants to talk about how they can get more people to book their flights directly from their website instead of using other websites or people who help sell tickets.

1. The headline is misleading and sensationalized, as it implies that there is a specific event or reason behind the share price movement of American Airlines, United Airlines, and Delta Air Lines today, while the article does not provide any clear explanation for why this is happening.
2. The article mixes different types of information without proper context or segregation, such as:
a. The promotion of Benzinga Pro service in the middle of the text, which seems to be irrelevant and unnecessary for readers who are looking for actual news or analysis.
b. The mention of United Airlines' reiterated outlook without explaining how it relates to American Airlines' lowered guidance or share price performance.
3. The article uses vague terms and comparisons that do not convey a clear message, such as:
a. "In sympathy" - this phrase implies a causal relationship between the companies without providing any evidence or reason for it.
b. "Rival" - this term is subjective and does not specify how United Airlines and Delta Air Lines are competing with American Airlines in terms of performance, strategy, or customer demand.
4. The article relies on outdated or irrelevant data, such as the full-year 2024 adjusted earnings expectations from United Airlines, which have no direct impact on the current share price situation and may not reflect the actual market conditions or investor sentiment.

1. Sell American Airlines shares (AAL) immediately as they are underperforming their rivals United Airlines (UAL) and Delta Air Lines (DAL). The company also lowered its guidance for adjusted operating margin, which is a negative sign for investors.
2. Buy United Airlines shares (UAL) as they have outperformed the market in the last six months and reiterated their earnings expectations. They are focusing on directing more bookings to their own platforms, which could increase their revenues and profitability in the long term.
3. Buy Delta Air Lines shares (DAL) as they have also outperformed the market in the last six months and have a strong balance sheet with $14 billion in cash and short-term investments. They are well positioned to benefit from the recovery of the airline industry and the increasing demand for travel.
4. Be aware of the risks involved in investing in the airline sector, as it is highly cyclical and affected by various external factors such as fuel prices, labor costs, competition, and consumer sentiment. The ongoing pandemic and its impact on travel demand could also pose challenges for these companies in the near term.
