A guest might be a member of your hotel loyalty program and/or a member of multiple airline frequent flier programs. In OPERA, there’s no limit to the number of memberships you can enroll the guest in, and you can choose from these multiple available memberships to decide which ones should be used for a particular reservation.
Enroll the guest within their Profile. You can then use their membership information — such as membership number, type, or level— in searches, reports, and bookings. Membership information is stored on both the guest profile and on the reservation.
