The Atlanta-based airline, which referred the September quarter as an "important milestone" in its recovery, posted $9.15 billion in revenue, easily surpassing the consensus estimate of $8.4 billion.
"Our September quarter marked an important milestone in our recovery, with our first quarterly profit since the start of the pandemic," said Delta CEO Ed Bastian. "Our revenues reached two-thirds of 2019 levels thanks to the industry-leading operational performance our people delivered through a busy summer, once again showing why they are the best in the business."
The airline also hinted that the recent rise in fuel prices might impact profitability in the upcoming quarter.
"While demand continues to improve, the recent rise in fuel prices will pressure our ability to remain profitable for the December quarter," Bastian said.
"As the recovery progresses, I am confident in our path to sustained profitability as we continue to provide best-in-class service to our customers, strengthen preference for our brand, while creating a simpler, more efficient airline," he added.
