System maintenance for sign-in and other account-related functions

All account-related functions such as sign-in, sign-up, and password reset for Cathay members on our website are temporarily unavailable between 22:00 12 May 2025 and 04:00 13 May 2025 (Hong Kong time) due to a system update to give you a better experience. Additionally, the Miles Plus Cash payment service is offline.

We apologise for any inconvenience this may cause. During this period, you can still access Manage Booking and Online Check-In using your booking reference or e-ticket number.

If you need to sign in to update your profile, please use our mobile app. For registering for promotional campaigns, please try again after the maintenance period.

Thank you for your patience and understanding.
