Only the acting host in a Zoom meeting can make someone else a co-host or the host. The acting host is either the person who created the meeting or, if that person isn't present, the first alternative host to join the meeting.

On Airbnb in 2026, the ability for a co-host to invite others depends entirely on the permission level granted by the primary host. If a co-host has been given "Full Access," they can indeed invite additional co-hosts to the listing. However, if they have limited access (such as only "Calendar" or "Messaging" permissions), they are restricted from managing the team. Even with full access, a co-host cannot change the primary host’s payout settings or tax information. For 2026 hosts, it is a "best practice" to only grant full access to trusted property managers. If you are a co-host looking to expand the team, check your "Co-hosts" tab under listing settings; if you don't see the "Invite" button, you will need the primary owner to either upgrade your permissions or send the invitation themselves.
