Delta sued CrowdStrike over the July 2024 software outage, seeking unspecified damages and alleging failures that contributed to the airline’s losses. CrowdStrike disputes Delta’s account and has argued that contract terms limit its potential liability. Neither side’s claims establish who is legally responsible: CrowdStrike reported that a judge partly granted and partly denied its motion to dismiss in May 2025, with discovery still ongoing as of the company’s July 31, 2026 filing.
What happened between Delta and CrowdStrike?
CrowdStrike disclosed that on July 19, 2024, it released a content configuration update for its Falcon sensor that caused crashes on certain Windows systems. The outage disrupted airline operations, including Delta’s flight schedule.
Delta filed suit in Fulton County, Georgia, on October 25, 2024. The case was later transferred to the Metro Atlanta Business Case Division. The dispute centers on competing accounts of the software update, the parties’ contractual and other duties, Delta’s recovery from the outage, and the losses Delta says it suffered.
Why is Delta suing CrowdStrike?
Delta’s complaint alleges computer trespass, trespass to personalty, breach of contract, intentional misrepresentation or fraud by omission, strict-liability product defect, gross negligence, and deceptive and unfair business practices. Delta seeks monetary damages, attorneys’ fees, and punitive damages, but did not specify the amounts in its complaint. These are allegations and requested remedies, not findings by a court.

#1 Best Overall
The Associated Press reported that Delta accused CrowdStrike of failing to test the update before its global rollout. Delta CEO Ed Bastian said in an August 8, 2024 SEC filing, “An operational disruption of this length and magnitude is unacceptable, and our customers and employees deserve better.”
How much did the CrowdStrike outage cost Delta?
Delta’s August 8, 2024 SEC filing said the disruption led to approximately 7,000 flight cancellations over five days. Delta said it was pursuing claims against CrowdStrike and Microsoft for at least $500 million in damages. The company’s estimates were:
Rank #2
- Ideal for Gifting
- Ideal for a bookworm
- Compact for travelling
| Delta’s estimate | Amount | What Delta said it represented |
|---|---|---|
| Direct revenue impact | $380 million | Primarily refunds and customer compensation |
| Non-fuel expenses | $170 million | Primarily customer reimbursements and crew-related costs |
| Reduced fuel expense | $50 million | Lower fuel costs due to canceled flights |
The $500 million figure was Delta’s stated damages claim, and the component figures were company estimates—not a court award or a finding that CrowdStrike was liable. The $50 million fuel reduction is a cost decrease, not an additional damage claim.
What did CrowdStrike say in response?
CrowdStrike rejected Delta’s accusations. In an August 5, 2024 letter reported by The Register, it said it had offered support within hours and alleged that Delta declined free on-site assistance. The company also rejected Delta’s gross-negligence allegation. Those statements are CrowdStrike’s account; they do not establish whether the offer or alleged refusal affected how long Delta’s recovery took.
The Associated Press reported that CrowdStrike called Delta’s claims misinformation and argued that the airline was shifting blame for its slow recovery. In its letter, CrowdStrike said Delta’s public threat of litigation “distracts from this work and has contributed to a misleading narrative that CrowdStrike is responsible for Delta’s IT decisions and response to the outage.”
CrowdStrike’s contract arguments
In its October 2024 federal complaint, CrowdStrike asked the court to declare that a June 30, 2022 Subscription Services Agreement governs any claim and limits liability to twice the fees paid for the relevant subscription term. It also argued that the agreement excludes indirect, incidental, punitive, or consequential damages. CrowdStrike further alleged that Delta’s own actions were primarily responsible for its losses.
Rank #4
These are arguments CrowdStrike asked a court to accept, not a ruling that the contract limits apply or that Delta caused its own losses. Whether contractual terms restrict particular claims or damages is a legal issue distinct from Delta’s allegations about the update and its effects.

The court repository identifies the May 16 order in case 24CV013621 as an order by Judge Kelly L. Ellerbe, but the accessible record did not provide the full text. It is therefore not possible to reliably say from that record which individual claims survived. The case’s status after CrowdStrike’s July 31, 2026 filing is not established here; the partial dismissal ruling was not a final verdict on liability.
