If you remain an active partner with V. Group, your SeaStars will expire 36 months from the date they are credited to your account. For clarity, your unused SeaStars will expire on a rolling 36 month basis.
If you have a period of inactivity for 12 months or more, all your Voyage access will be frozen for a further 12 months. If there is no activity within the 24 months period, all SeaStar points will automatically expire.
