Delta Air Lines Inc.’s stock shot up toward a four-month high in premarket trading Thursday after the air carrier topped Wall Street’s estimates for second-quarter profit and revenue and restored its full-year guidance.

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.

The carrier will report earnings Thursday, providing an update on the health of the travel sector and the U.S. economy.
