The overhead compartments have a limited amount of space. We therefore kindly request that you also stow items under the seat in front. You are also welcome to help yourself to an anti-dirt cover, which can be found near the boarding gate, so that you can prevent your items from getting dirty when putting them under the seat in front. If you would like to use a cover, please place it over your baggage before entering the cabin so that you can help us to alleviate congestion on board. We thank you in advance for your cooperation.
