Delta Air Lines saw its operating profit decrease 7% to $1.84 billion in the third quarter, as it took a $120 million hit from storms that hit the Southeast USA in September.

Operating revenue increased 6% year-over-year, to $11.1 billion, but operating expenses were up 8% at $9.22 billion, says the Atlanta-based carrier.

The $130 million year-over-year decline in operating profit at Delta is roughly equal to the financial impact of Hurricane Irma, which hit South Florida in September and prompted the cancellation of roughly 2,200 flights.

The airline's adjusted operating margin was 16% in the third quarter, in line with its 15.5-16.5% guidance.

Net profit decreased 6% to $1.18 billion.

Passenger unit revenue increased 1.9% to 13.4 cents, and unit costs excluding fuel, special items and profit sharing rose 4.8% to 10.05 cents in the third quarter. Average fuel expenses climbed 13.2% to $1.68 per gallon.

Traffic was up 3.4% on capacity increased 1.6% in the third quarter.
