Silver members receive all Green tier benefits and unlock additional advantages, including priority check-in at Business Class counters, access to Business Class lounges, and expedited baggage handling. They also benefit from increased Asia Miles earning rates when shopping or dining.

Gold tier members are entitled to an extra piece of checked baggage and are guaranteed an Economy seat on Cathay Pacific flights. Additionally, Gold members receive two complimentary Business Class lounge passes and exclusive upgrades, alongside enhanced earning rates for Asia Miles.

Diamond tier members benefit from First Class check-in, access to all First Class and Business Class lounges, and the privilege of inviting guests. These members also receive priority baggage handling and exclusive offers at partner hotels and restaurants.
