American Airlines Group shares rose 3.52% to $13.82 Friday afternoon as a diplomatic proposal involving the reopening of the Strait of Hormuz reduced geopolitical pressure on global energy markets. Iran's Foreign Minister confirmed that Tehran had submitted the United States a formal seven-day plan that also included restarting stalled discussions on Iran's nuclear program. West Texas Intermediate and Brent crude futures fell after the announcement, easing one of airlines' largest and most volatile costs. Lower jet-fuel prices could improve American Airlines' near-term margin outlook as it manages a heavy debt load and competitive domestic pricing ahead of the fourth-quarter holiday travel season.
