Turkish Airlines allows cabin bags up to 55x40x23cm in the overhead locker, and it's included with economy class tickets. The allowance also comes with a weight limit, typically 8kg, so lightweight luggage is worth prioritising.

Turkish Airlines flies to more destinations than almost any other airline, connecting Europe, the Middle East, Africa and Asia through Istanbul. If you're transiting or flying a longer route, getting the cabin bag size right means one less thing to worry about.

The Flight Knight bags listed below all fall within Turkish Airlines' allowance. Pick something that suits your trip length and packing style.
