You can always bring at least one carry-on bag and one personal item, such as a small handbag or laptop in the cabin free of charge.
Your baggage allowance depends on your ticket type. All carry-on baggage must be within the size and weight limits and fit under the seat in front of you. Coats and jackets can be stowed in the overhead compartment. Duty-free and airport purchases counts as part of your carry-on.
