Some Delta passengers whose flights were canceled during a July tech outage that impacted Delta and CrowdStrike have filed a class action lawsuit against Delta. The lawsuit alleges that Delta refused to provide automatic refunds for canceled flights and only offered partial reimbursements or vouchers to passengers who signed liability waivers. CrowdStrike and Microsoft have said Delta ignored their offers of help and suggested Delta's own outdated IT systems exacerbated the problems. Delta said it has invested billions in IT recently and said CrowdStrike was unavailable for help.
