Shares for top U.S. airlines, including Delta Air Lines, Southwest Airlines and United Airlines, were largely unchanged in trading on Wall Street on Monday after the carriers faced a now resolved system-wide outage, leading to flight delays across the country.
Delta -- which posted on Twitter earlier in the day that it did not have a specific timeframe for when it would get its system back online -- said a third-party technical issue was resolved and no flight cancellations are expected.
Southwest also wrote on the social media platform that it was back to functionality after the glitch.
"As of 6:05am CDT, Southwest Airlines has lifted an internal ground stop implemented for about 40 minutes this morning during an outage with a vendor that services multiple carriers with data used in flight planning. Scattered flight delays are anticipated," the Dallas-based carrier said in an emailed statement.
|UAL||UNITED AIRLINES HLDG.||50.52||-1.53||-2.94%|
|DAL||DELTA AIR LINES INC.||46.24||-0.72||-1.53%|
|LUV||SOUTHWEST AIRLINES CO.||56.92||+0.84||+1.50%|
United wrote on Twitter that the outage was impacting its ability to create release paperwork, leading to delays.
"The issue has been resolved. Contact individual #airlines for information on specific delays," the Federal Aviation Administration wrote in a tweet.
Southwest and American Airlines previously said customers would see continued flight cancellations as a result of the grounding of Boeing’s Max jets earlier this month following two recent crashes involving the aircraft.
