Delta Air Lines expects non-fuel unit costs to increase 3%-4% in Q4

"With a step up in capacity restoration, we reported sequential improvement in December quarter unit cost performance. In 2023, we are confident in completing our network rebuild and delivering the benefits of scale and efficiency as we move through the year, resulting in a 2 to 4 percent decline in non-fuel unit costs year-over-year, including all expected labor cost increases," said Dan Janki, Delta’s chief financial officer. For the March quarter, we expect non-fuel unit costs to increase 3 to 4 percent year-over-year, including a full quarter impact from labor cost increases and finalizing the rebuild of our network for the peak summer period. Our outlooks for the March quarter and full year are consistent with our cost framework provided to investors on December 14, updated for all expected labor cost increases."
