NEW YORK, Oct 11 (Reuters) - Delta Air Lines' third-quarter adjusted pre-tax income fell 9.5 percent to $1.7 billion versus the year prior, hit by a $120 million negative impact from Hurricane Irma in September, the company said on Wednesday.
The No. 2 U.S. carrier by passenger traffic said its quarterly operating revenue rose 5.5 percent to $11.1 billion, in spite of a $140 million reduction from the storm.
Despite the storm-related impact, Delta beat analyst expectations. Its adjusted earnings per share were $1.57 versus the consensus forecast of $1.53 per share, according to Thomson Reuters I/B/E/S.
Delta's quarterly passenger unit revenue rose 1.9 percent on 1.6 percent higher capacity. Its passenger revenue increased $328 million, including $160 million from fare segmentation initiatives.
"Having just completed the busiest summer travel season in our history, we have good momentum, a determined team and a solid pipeline of initiatives to grow earnings and margins," Delta Chief Executive Officer Ed Bastian said in a statement.
The carrier forecast it would increase its fourth-quarter year-over-year passenger unit revenue by between 2 percent and 4 percent and have an operating margin of between 11 percent and 13 percent. (Reporting by Alana Wise; Editing by W Simon)
