Hopes for a U.S.-Iran peace deal are pushing oil prices down sharply. Airlines, which burn through enormous amounts of fuel, are soaring as a result — Delta, United, and MGM Resorts all ranked among the top S&P 500 gainers today.

## Idea

Airlines are extremely sensitive to fuel costs — oil is one of their biggest expenses. When crude drops 3% in a single day on credible peace signals between the U.S. and Iran, it directly boosts airline profit margins. Delta and United already surged today, and if a formal deal restores normal shipping through the Strait of Hormuz, oil could keep falling — giving these stocks even more upside. The trade is compelling because you're not just betting on a peace deal; you're betting on lower fuel costs that improve earnings for months to come.
