Yes, Qatar Airways maintains a fairly strict dress code, though it differs significantly between "Standard Passengers" and those traveling on "Staff Travel" (ID90) tickets. For general passengers in 2026, the airline expects attire that is respectful of the cultural norms of Qatar; this means shoulders and knees should generally be covered, and clothing with offensive graphics or extremely revealing cuts may lead to a denial of boarding. In Business and First Class, "Smart Casual" is the unofficial standard, with most passengers opting for chinos, collared shirts, or elegant dresses. For those using staff travel benefits, the code is much more rigid: denim must be dark and well-fitted (no rips), flip-flops are strictly forbidden, and "gym wear" or leggings are generally not permitted in premium cabins. Because Qatar is a conservative Islamic country, the airline's ground staff in Doha are particularly observant of these rules. Travelers in 2026 are advised to avoid "beachwear" or very short skirts during their flight to ensure a smooth boarding process and to show cultural sensitivity when transiting through the award-winning Hamad International Airport.
