Deem recommends the second option. Restricting at the Superdomain level will block Basic Economy for all of your clients’ sites, not just individual sites. You may have a client that insists on having Basic Economy displayed, where all others would like them blocked completely. The second option allows for more flexibility between the sites.
Note: Deem can only block non-changeable Basic Economy Fares, those fares which allow changes cannot be blocked.
Helpful Hint: If you are blocking Basic Economy within a site, you may want to add a Dynamic Message indicating that Basic Economy has been removed from your site. Adding this message may help with questions or concerns around why you are not showing the lowest available rate.
