Delta Air Lines has significantly lowered its profit outlook, citing weakening demand and growing economic uncertainty. The airline has warned investors that its profit forecast has been slashed in half, leading to a sharp decline in its stock price. This downturn reflects a broader trend affecting the airline industry, as competitors such as United and American Airlines also adjust their expectations amid similar concerns. Delta is experiencing declining consumer and corporate confidence, which has resulted in slower domestic travel demand. Despite a previous optimistic outlook, the company’s recent guidance suggests a challenging economic landscape ahead.
