Delta put some figures on its plans to recover at least $500 million in damages from CrowdStrike and Microsoft.

In an SEC filing, Delta broke down the outage impact this way:

  • $380 million direct revenue impact due to refunds and customer compensation with SkyMiles or cash.
  • $170 million in non-fuel expenses due to operational recovery, which includes customer expense reimbursement and crew costs.
  • $50 million in gains from lower fuel expenses due to 7,000 flight cancellations.

Add it up and you get to Delta's $500 million figure.

CrowdStrike and Microsoft have volleyed letters with Delta and the core points against Delta were:

  • Both vendors offered to help Delta, but didn't get responses.
  • Delta's creaky infrastructure and IT practices shouldn't be put on vendors.
  • Delta has to explain why it couldn't recover when competitors restored operations faster.

What's next? More volleying between a customer and two vendors and a handful of lawsuits. The discovery process on Delta's technical architecture is going to be fascinating to watch and fodder for IT management case studies in the future.
