Delta Air Lines saw its profits more than double in the fourth quarter last year, helped by strong travel demand, even as it trimmed its earnings expectations for 2024, the US carrier said Friday. The company reported net income of over $2 billion for the October to December period, up from $828 million for the same period in 2022. Its revenue jumped to $14.2 billion for the quarter, helped by “the highest holiday travel volumes in its history.” “In 2024, demand for air travel remains strong and our customer base is in a healthy financial position with travel a top priority,” said Delta chief executive Ed Bastian in a statement. But in its earnings report, Delta lowered its full-year earnings forecast for 2024 slightly — from over $7 per share projected in 2022, to $6 to $7 per share now. Delta shares slumped 5.2 percent in premarket trading on Friday. For the first quarter this year, Delta expects its revenue to rise by three percent to six percent, and anticipates earnings per share of between 25 cents and 50 cents. This should come on the back of strong international travel demand and “a positive inflection in the domestic environment,” said Delta president Glen Hauenstein. For all of 2023, Hauenstein added that the company delivered a record $54.7 billion in revenue, 20 percent above 2022. On Friday, the company also announced a deal with Airbus to buy 20 A350-1000 widebody aircraft, with deliveries set to begin in 2026.
