WASHINGTON — (CNN) Delta Air Lines says the total bill for its devastating computer outage will come to $150 million.

The problem occurred when the company lost power at its operations center in Atlanta early on the morning of Aug. 8, causing computers needed to book in passengers and fly jets to be down for nearly five hours.

The airline eventually canceled about 1,000 flights on the day of the outage and ground an additional 1,000 flights over the following two days.

It also agreed to give affected customers refunds and vouchers for future travel.

The cost of the outage was disclosed in a presentation Delta made to investors Wednesday.

The losses came out of pre-tax profits, but the airline did not provide a break down of the various costs.

Delta shares were slightly lower in premarket trading.

Delta is not the only airline to experience these kinds of computer problems recently.

Southwest was hit with a computer outage in July that also canceled flights over a three day period. British Airways was hit with its own computer problems on Monday.
