Six response headers every browser and security scanner checks for. They are set once at the server and cost nothing to add. Anyone can verify this list in about ten seconds with curl.
This site could not be reached when we ran the check, so its headers were not measured. It is not recorded as failing.

We rebuild sites clean, and we do not stop until every category comes back green, including all six security headers, or your money back. You own everything, no lock-in.
We measure a public website only. This says nothing about how United Airlines handles data internally, and nothing here is a statement about any incident. Headers were read with a single request following redirects on September 1, 2026.
