During your journey, you (and your children) must be in possession of the necessary travel documents and visas according to the laws of the countries of departure, transit and arrival. Brussels Airlines is not liable for the consequences of failure to possess the necessary documents and/or visas.
Legislation in the area of travel documents and visas is very complicated and extensive. We therefore advise you, in case of doubt, to contact the embassies or consulates of the countries at which you will touch down in transit and the countries that you wish to visit, a few weeks prior to your journey. They will be able to provide you with the most accurate information.
