If you are a Diamond member of Cathay Pacific’s Marco Polo Club you might not be aware there is a further – higher – tier to aspire to: Diamond Plus.
According to a CX spokesperson, Diamond Plus and Diamond members are “considered in the same tier in every aspect”. However, Diamond Plus get extra perks consisting of
• Nomination of one companion to the Diamond tier
• Access to CX First Class lounges regardless which airline they are flying
• The services of a dedicated Diamond Plus Service Team
The Diamond Plus tier is not to be confused with CX’s Lifetime members, which was how the airline previously recognised the custom of very frequent fliers.
