It is the passenger’s responsibility when booking their trip to ensure that their travel documents meet the requirements for entry into the country of destination. You may need to apply for a visa (or other travel document) to enter your country of destination, or even a country where you need to change planes to continue your journey. For more information, please visit the website of the Ministry of Foreign Affairs.
