The information given below by CORSAIR is provided for guidance and is subject to change. It is your responsibility to find out from the competent authorities about the documents and the various formalities which are required to enter the country of destination and transit on the date of your trip.
A passenger who is refused check-in or boarding for reasons based on non-compliant documents would automatically lose his ticket. CORSAIR cannot be held responsible in the event of denied boarding or in the case of denied access to the country of destination for failure to comply with police, health, or customs formalities.

Health formalities: vaccinations may be obligatory (especially against yellow fever for some African countries) or recommended depending on the country. In any case, we recommend that you seek advice from your doctor at least six weeks before your departure.
