Thanks everyone, we are traveling with Turkish Airlines from Doha, we are bringing amongst 230 kgs of other items a Afghanistan 3.5 x 2.5 mts hand made rug with us, and it will be folded, but the airline said if it was a rolled carpet you have to prebook it as over sized luggage when you book your ticket, and to make sure there is a solid type of cylinder inside so the carpet does not bend and get damaged.
