While subscription stacking is permitted and allows members to enjoy the combined benefits of multiple programs, the total number of Status Nights that can be counted on an annual basis as part of the purchase of subscriptions is capped at 30 Status Nights.
This cap does not apply to Bonus Offers such as Fast Track promotions or other limited-time campaigns.
For example, if you purchased the following subscriptions: 'Explorer + Voyager' (which grant a total of 50 Status Nights), the total number of Status Nights credited as part of the purchase of those programs will still be limited to 30.
