Airlines are experiencing a significant rally in pre-market trading, primarily driven by a sharp drop in oil prices after the United States and Iran announced a pause in hostilities. Lower fuel costs are a major tailwind for the sector, directly improving profitability. Adding to the positive sentiment are reports that United Airlines had explored a potential merger with Delta Air Lines. Although the talks have reportedly ended, the news highlights the potential for major consolidation within the industry, which could lead to improved pricing power and efficiency.
