Delta’s president warned revenues may not normalize for “two years or more.”The airline also posted a wider-than-expected loss during the quarter.Large airlines like Delta have been particularly challenged in the pandemic because they previously relied heavily on business travel and sprawling international networks, two areas that have been hard-hit in recent months.Delta has spent recent months retiring dozens of aircraft and reducing its footprint to cut costs. About 18,000 Delta employees, about a fifth of its pre-pandemic workforce, accepted buyouts and early retirement packages, prompting a $3.1 billion restructuring charge.Airlines received portions of $25 billion in federal payroll support Congress passed this spring but talks between the Trump administration and Congress for additional airline aid have repeatedly derailed.Here’s how Delta performed compared with what Wall Street expected, based on average estimates compiled by Refinitiv:Adjusted EPS: a loss of $3.30 versus an expected loss of $3Revenue: $3.06 billion versus $3.11 billion, expectedMore airlines are competing for price-sensitive leisure travelers within the United States but demand has struggled, despite an uptick from multi-decade lows hit in April.

Delta got down to $18 million a day in September, an improvement but still far off its goal of breaking even by the end of the year.”While our September quarter results demonstrate the magnitude of the pandemic on our business, we have been encouraged as more customers travel and we are seeing a path of progressive improvement in our revenues, financial results and daily cash burn,” Delta’s CEO Ed Bastian said in an earnings release.Since the pandemic began, Delta has posted more than $11 billion in losses.On an adjusted basis, Delta lost $3.30 per share, more than the $3 per share loss analysts polled by Refinitiv were expecting.Delta has already retired dozens of planes to cut costs.
