passengerinfo-api.delta.com is a subdomain owned by Delta Air Lines, one of the world's largest airlines. It functions as an API endpoint, likely handling passenger information behind the scenes of Delta's main website and mobile apps. For an internal-facing service like this, the security and infrastructure are exactly what you'd expect from a major airline: a valid SSL certificate, enforced HTTPS, and hosting on Akamai's enterprise-grade network. There are no blacklists or malware warnings, and the domain is clearly part of a trusted brand. If you're wondering whether passengerinfo-api.delta.com is a scam or fake, the evidence points strongly to it being a legitimate part of Delta's digital ecosystem. The bot protection and lack of public-facing pages are normal for an API. For travelers, this site isn't something you'd visit directly, but it powers the data flow that makes your Delta experience work. You can trust that it's safe.

Where the score comes from
Strong security setup with a valid SSL certificate from a respected issuer and enforced HTTPS. No malware or phishing flags detected. This is exactly what you'd expect from a legitimate API endpoint handling passenger data.
The domain is a subdomain of delta.com, a well-known major airline with a long-established brand. While the subdomain's individual registration isn't visible, the parent company's identity is clear and trustworthy.
Hosted on Akamai, a leading content delivery network used by many large enterprises. Fast load times and clean DNS resolution support a reliable backend service. The lack of DNSSEC is not a red flag for this type of service.
No blacklists or security warnings exist for this site. The absence of independent reviews or web archive history is expected for a backend API rather than a public-facing site. Overall, no reputation concerns.
This is an API subdomain, not a consumer website, so the absence of an about page or contact details is normal. Bot protection blocking inspection is standard for APIs but naturally limits visibility.
Legal pages like privacy and terms are not directly found on this subdomain, but as part of Delta Air Lines' infrastructure, they are almost certainly covered under the parent company's policies. This is not a compliance gap for a subdomain of an established airline.
