Delta fliers faced delays, cancellations and more headaches Wednesday as the Atlanta-based airline struggled with its computer systems for the third straight day.

Nearly 300 flights were canceled by the afternoon, in addition to the 800 scrapped Tuesday and 1,000 canceled Monday. Hundreds of other flights were delayed Wednesday.

Hundreds of thousands of passengers have been stranded overnight throughout the ordeal, many spending the night in airports around the globe. Others were put up in hotels by Delta, including 2,300 in Atlanta alone Tuesday night.

The system the airline uses to check in and board passengers as well as dispatch its planes is still slow, Gil West, Delta's chief operating officer said Tuesday.

The problems started Monday when, according to a statement by West, equipment failed at the airline's headquarters.

It caused a loss of power, and key systems and equipment did not switch over to backups.

Delta extended a travel-waiver policy to help stranded passengers rearrange their travel plans. It offered refunds and $200 in travel vouchers to people whose flights were canceled or delayed at least three hours.

Oil rig's fuel tanks breached

Coast guard officials say two fuel tanks have been breached on an oil rig that was blown onto a remote Scottish beach.

The Transocean Winner was being towed when it broke free of its tug and ran aground on the Isle of Lewis off Scotland's west coast on Monday.

The Maritime and Coastguard Agency says the rig is carrying 280 tons of diesel in several tanks.

The agency says salvage workers boarded the rig Tuesday and “discovered that two of the fuel tanks appear to have been breached.” Poor weather prevented the workers returning to the rig Wednesday.

Local politicians have called for an emergency towing vessel to be based in the area.

Terror suit against Twitter tossed

A federal judge in San Francisco has dismissed a lawsuit accusing Twitter of supporting the Islamic State group.

The families of two men killed in Jordan claimed that Twitter had contributed to their deaths by allowing the group to sign up for and use Twitter accounts.

The judge agreed with Twitter that the company cannot be held liable because federal law protects service providers that merely offer platforms for speech, without creating the speech itself.

Lloyd “Carl” Fields Jr. and James Damon Creach were shot and killed in 2015 while working as U.S. government contractors in Amman, Jordan, according to the lawsuit.
