Delta Air Lines, the world’s largest carrier by revenue, reported upbeat second quarter results and reinstated its guidance as growing economic clarity deflects headwinds resulting from a global trade war.

Delta Air Lines Inc. reinstated a profit outlook for the year and said travelers are coming back, prompting its stock to surge amid a fresh sense of confidence in the beaten-down US consumer.

After withdrawing its outlook in April, Delta is again forecasting a profit—though at a significantly lower level than originally projected.

Analysts expect that airlines will have a tepid earnings season as tariff uncertainty and declining U.S. dollar weigh on the industry.

The demand stabilization was enough to push Delta's top and bottom lines ahead of Wall Street expectations for the second quarter. Revenue was flat at $16.65 billion, in the quarter ended June 30, beating the $15.46 billion analysts were forecasting. Total revenue per available seat mile, a key industry metric, fell 4%, to 21 cents.

Delta Air Lines restored its financial guidance for the year, months after scrapping its initial outlook in response to the ongoing global trade war.
