No. Crowdstrike took down all Windows machines. It took hours to a day to get most of them back up for everyone.
Southwest's application stack was most resilient and they had booking systems up and running within the day. Other airlines had their application layer synced overnight.
Delta's application layer could not recover. If all their computers had rebooted at nearly the same time, they'd have the same situation where they were offline for days. Those cascading failures had nothing to do with the initial Windows crash and lockup. Then Delta tried to cover themselves by claiming they were still dealing with the initial Crowdstrike problems for days but Microsoft refuted that and eventually Delta had to disclose the real problem to regulators and investors.
