When booking your next trip:
Choose the lowest available fare (v.club fare). Your v.club membership will be automatically added to the shopping cart. Create a new account or use an existing one. When you complete your booking you become a v.club member.
NOTE: The passenger 1 becomes the membership owner. Make sure to enter your information as it appears on your official documents and keep in mind that the email that you register will be your v.club username from now on.
