Airlines stocks took off on Thursday, boosted by Delta reporting better-than-expected earnings and reinstating its full-year guidance. Here are the key chart levels to monitor for shares of three major U.

For the most recent quarter, analysts expect Delta to report earnings of $2.03 per share on revenue of $16.18 billion for the upcoming quarter. This reflects a decrease compared to the same quarter last year when the company reported earnings of $2.36 per share on revenue of $16.66 billion.

Delta Air Lines is positioned in the middle among its peers for Consensus rating. It ranks at the bottom for Revenue Growth. In terms of Gross Profit, Delta Air Lines is at the top among its peers. For Return on Equity, Delta Air Lines is positioned in the middle compared to its peers.

Delta Air Lines released their latest earnings report Thursday, saying that the results so far for the quarter were in line with expectations from April.

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

A big reason the stock spiked 13% on Thursday was because of the outlook. It reinstated its annual guidance, calling for earnings of $5.25 to $6.25 per share for the full fiscal year. That’s down from the Q4 guidance but the company did not then foresee the first quarter economic slowdown or massive tariff impact.

Delta, the first of the U.S. airlines to report results, expects adjusted earnings per share of between $1.25 and $1.75 in the third quarter, compared with Wall Street analysts' forecast for $1.31 a share. It also said it expects revenue that's flat to up 4%, topping forecasts for a 1.4% sales increase.

Delta Air Lines' strong earnings and projected growth provided an early boom for the airline industry as the rest of the major carriers prepare to report.
