Microsoft has accused Delta Air Lines of providing misleading information regarding the airline's recent operational meltdown. According to Microsoft, the key system failures were not due to their technology but rather issues with Delta's crew scheduling systems managed by IBM.
During the period from July 19 to July 23, Microsoft reportedly offered assistance to Delta at no cost. Despite these offers, Delta declined Microsoft's help. In a letter, Microsoft stated that its employees were ready to assist each day but were consistently turned away by Delta IT personnel who claimed they were "all good."
The disruption led to significant operational challenges for Delta, including losing track of crew members and making terminal announcements in search of available pilots. The airline's crew scheduling systems collapsed and required several days to recover, running multiple instances in parallel which created additional synchronization problems.
