周四盘前，达美航空（Delta Air Lines，股票代码：DAL）股价大跌5.94%，引发投资者关注。此次下跌主要源于美国政府实施新的全面互惠关税政策，引发市场对经济前景的担忧。
据报道，美国主要航空公司股价在盘前普遍下跌。除达美航空外，捷蓝航空下跌4.6%，美国航空下跌2.8%，美联航下跌3.5%，西南航空下跌2.9%。分析师指出，新的关税政策可能导致经济增长放缓，进而影响消费者的旅游支出。
晨星研究公司分析师丹·瓦西奥莱克（Dan Wasiolek）表示："旅游属于自由支配性消费，无法避免受到潜在关税战带来的经济增长放缓影响。"受此影响，美国主要航空公司已下调了盈利预期，进一步加剧了投资者的担忧情绪。截至目前，道琼斯美国航空指数已下跌24.22%，反映出整个行业面临的挑战。
