This is not meant to be an exhaustive search of all the best Black Friday sales, however each regional Qatar page (e.g. https://www.qatarairways.com/en-ro/o...ck-friday.html for Romania) has a selection of fares. I've spent no more than 15 minutes and found what appears to be reasonable fares as I've put below. Not warranting that they are super deals or the cheapest ever, but generally what look to be fairly reasonable price points:
