A CNAME (Canonical Name) is a type of DNS record that is used to link an alias name to another true or canonical domain name. For instance, www.example.com might link to example.com.
In the case of the white label, the true or CNAME is whitelabel.b2b.skyscanner.net.
The CNAME allows you to use an alias to hide the Skyscanner url and use the url of your choice, for example a subdomain of your domain: flights.mytravelsite.com.
