Underground Plus
Underground Plus is the name for the perks and benefits bundled into every membership tier — Corporate Affiliate, Principal Circle, and Sovereign Partner alike. It is not a fourth, separately priced tier: there is no additional subscription to buy into Plus on its own.
The categories below describe what each part of the program is intended to cover. Enrollment and activation for most categories depend on confirmed partner agreements that are not yet in place. Where a category is not yet active, it is marked “Program in preparation” rather than presented as something you can book or claim today.
Premium Perks
Curated discounts and preferential terms with select partner brands across travel, hospitality, and lifestyle categories.
Insurance
Preferential terms on travel, health, or liability coverage, arranged through partner insurers where available in a member's jurisdiction.
Underground Travel
Booking assistance and preferential terms for flights and ground logistics through a partner travel desk.
Hotel Booking
Preferential rates at partner hotels and properties for personal and business travel.
Car Rental
Preferential terms with partner car rental providers in the markets where Underground operates.
Exclusive Club
Invitations to a private lounge and club network in select cities, for members passing through or based there.
Member Rewards
A recognition program tied to membership tenure and engagement with the network.
Underground Credit Cards
A co-branded card program offering member benefits, contingent on a confirmed banking partner and available only where that partner can issue.
Workspaces
Access to partner co-working and meeting space in Underground's hub cities.
Status of this program
Underground Plus is in preparation. Most categories above depend on confirmed partnerships — with insurers, travel and hospitality providers, a banking partner for the card program, and venue operators for the club network — that are not yet finalized. Nothing on this page should be read as an active, bookable benefit until Underground confirms a category is live for your tier and jurisdiction.
