DAR - Dar Es Salaam new T3
Inbound: Yes for first and business class travellers at immigration ( did not try as we were in Y).
Outbound: Yes, there is a whole separate premium area with comfy armchairs dedicated check in desks - not operational for our flight, passport control with seats and security at the far left. (though we checked in at the regular SP desks and were handed over lounge invitations from there). before entering a staff verifies the eligibility. That area leads to a lift going directly to the CIP Lounge.
