Status Points determine your Cathay membership tier and the benefits you receive. They reset to zero at the start of each new Cathay membership year upon renewal, upgrade, or downgrade. In contrast, Asia Miles act as a currency for redeeming flights and lifestyle rewards, and are valid for three years. While Status Points help you progress through membership tiers, Asia Miles enable you to enjoy travel and lifestyle experiences and purchases.

The Cathay membership tiers encompass four levels—Green, Silver, Gold, and Diamond—each tier recognises your travel with us and offers increasing benefits as you move through the programme. 

Green members receive foundational Cathay membership benefits, including flight promotions and priority check-in 48 hours prior to takeoff. These individuals also have the ability to secure seats with extra legroom by spending Asia Miles, depending on seat availability, and are given complimentary 48-hour access to the PressReader platform with every reservation.

Silver members are granted all the perks associated with the Green level, paired with priority check-in at Business class counters, entry into selected Business class lounges, and priority baggage handling. This upgraded status also provides enhanced Asia Miles earning whenever you shop or dine with our partners.

Gold members can check in one additional piece of baggage and can hold guaranteed seating in Economy on all Cathay Pacific flights. Gold members also receive two complimentary Business class lounge passes and upgrade prospects, combined with enhanced rates for collecting Asia Miles.

Diamond members enjoy the convenience of First-class check-in, admission to all First class and Business class lounges, and the privilege of bringing companions along. Diamond members receive priority baggage handling and exclusive offers at selected partner hotels and dining establishments.
