Turkish Airlines actually sets its official economy cabin baggage weight limit at 8 kilograms (approximately 18 pounds) rather than 7 kilograms. If a passenger's carry-on bag exceeds this 8-kilogram threshold or surpasses the permitted physical dimensions during gate checks, airline staff have the authority to require the bag to be checked into the aircraft cargo hold. When this occurs, passengers may be required to pay excess baggage fees depending on their specific fare class, ticket type, and route structure. To prevent this, travelers should repack heavy items into checked luggage or personal items before security screening.
