Delta Air Lines (NYSE:DAL) shares gained about 4.6% in premarket trading Monday after the airline lifted its revenue outlook for the first quarter.
The carrier now anticipates revenue growth in the high-single-digit range for the quarter, compared with its earlier forecast of 5% to 7% growth. Delta added that it still expects earnings to fall within the range previously provided.
The airline said capacity growth during the quarter was affected by winter storms. According to company presentation materials, non-fuel unit costs for the March quarter are projected to increase at a mid-single-digit pace year over year, reflecting reduced capacity and higher operating expenses.
