It is recommended that guests are fully vaccinated against COVID-19, if they are eligible.
While vaccination documents will not be required to board, we will ask that guests disclose their vaccination status to us prior to boarding (via the app, on our website, or at the terminal). We recommend they bring their vaccination documents with them, as local authorities or businesses in some destinations require it for entrance.
