They said some JetBlue, Southwest and United flights were temporarily delayed due to the nationwide technical issue.
"Several U.S. #airlines are experiencing computer issues this morning," the Federal Aviation Administration said on Twitter, tagging United, Southwest, JetBlue, Alaska and Delta airlines. "Please contact your airline directly for flight information and updates."
Gene and Mary Ann Shannon, of Woodbridge, arrived at Bradley Monday morning thinking their flight was on time, only to find out it was delayed.
Many of the airlines were telling passengers who had complained on Twitter that they were dealing with a technical issue. American Airlines identified AeroData, which provides airlines with flight software, as the culprit.
"AeroData is currently experiencing a technical issue that is impacting multiple carriers. They're working on a fix as quickly as they can," American Airlines replied to one person Monday morning.
Delta said before 7 a.m. ET that it was "experiencing a System-Wide Outage we are working diligently to get it back up and running."
