Cabin bags

What the official page says

Everyone can bring one small under seat cabin bag per person on board for free. It can be a maximum size of 45 x 36 x 20 cm (including any handles and wheels) and must be kept under the seat in front of you. Your bag can weigh up to 15kg. If you'd also like to bring a large cabin bag on board (max. 56 x 45 x 25 cm, including any handles and wheels), you have the option to book a large cabin bag for your flight.
