hi Foufa , i'm Tunisian i work currently in Qatar airways , the joining allowance is of 50 KGs and it should be loaded in a different flight (than the one you're coming on board) in advance at least of three days so that you get it as soon as you arrive to Doha , still few custom fees and things you have to pay at the cargo center that may reach 200 ryals , which makes it not 100% free ;)
