Delta Air Lines shares jumped 3.1% to close at $69.46 after the Supreme Court struck down Trump-era tariffs, removing import levies on equipment and parts. The rally reflects investor relief over lower input costs for airlines dependent on global supply chains.

With existing tariffs invalidated, Delta may see reduced operating expenses, supporting margin expansion. However, the administration’s proposed 10% global tariff introduces uncertainty over future cost savings.

This rally follows a 4.9% drop on fuel-cost concerns and sits among 19 price moves over 5% in the last year. Trading near a 52-week high of $75.35, the stock remains flat year to date, highlighting mixed volatility and valuation dynamics.
