it doesnt work like this , while the luggage rules regarding elites are thankfully standard across all skyteam members (there are exceptions of course but its way better than oneworld or star alliance) , no elite status or ticket types of any kind allow you to check 4 luggages for free

About status , i think its 1 max , but it can be 2 if you travel with light hand luggage , are really nice to checkin agent and he/she ask you if you would like to check your extra luggage

If you travel in business class then you need to check the rules of each airline you want to fly with , and as far as i know you can check 2 luggages in most cases

I remember that kenya airways and saudia are pretty generous about luggages even in travelling in economy (2 pieces) , otherwise the other airlines are usually allowing you the same (0 or 1 piece , depends on fares)

So if you combine luggage allowance in business + a status then you could check 3 luggages for free maximum (or included in the price) , if you want to have 4 you will need to pay
