Yes, you can typically bring both a carry-on bag and a personal item (like a backpack) on Turkish Airlines in 2026, but the specific allowances depend on your class of travel. For Economy Class passengers, you are allowed one cabin bag weighing up to 8kg (max dimensions 55x40x23 cm) and one personal item, such as a handbag, camera bag, or a laptop/small backpack that can fit under the seat in front of you. Business Class passengers are allowed two cabin bags (8kg each) plus one personal item. Turkish Airlines is known for being relatively strict about these dimensions at major hubs like Istanbul (IST). It is important to ensure your backpack is not an "oversized" hiking pack, as security or gate agents may insist it be checked if it exceeds the "personal item" footprint. Additionally, items like umbrellas, walking sticks, and baby food are generally permitted in addition to your baggage. For a smooth 2026 journey, always verify your specific "Baggage Allowance" in the Turkish Airlines mobile app, as some "EcoFly" or promotional fares on certain routes may have more restrictive cabin policies.
