You will find these business seats on most flight to Africa, except South African routes, most European routes, near east routes (ozbekistan etc), middle east routes. So anything up to 6-7 hours TK is installing these seats, and anything longer you will get the lie-flat business cabin.

they are trying to install only 2 types of buiness seats now, lie flat or these new recliners. anything else you get will be either older planes not refurbished yet or leased.
