How do I calculate Cathay Pacific mixed cabin miles?

Calculating Asia Miles for mixed cabin itineraries on Cathay Pacific or Oneworld partners can be complex. When your flight includes different classes—such as Economy and Business—the miles required are determined by a proportional distance formula. This calculator automates the Asia Miles rules for mixed cabins, saving you the hassle of manual math.

According to the Asia Miles Award Chart, the calculation uses a weighted average of the actual flown distance for each segment.

"If your itinerary involves mixed classes, the total miles required will be calculated based on the proportional distance of each flight segment."

Why book mixed cabins?

Mixed cabin redemptions allow travelers to optimize their Asia Miles. If Business Class is unavailable on a short connecting flight, you can fly Economy for that leg and still secure Business Class for the long-haul segment, saving miles overall while ensuring comfort on the longest part of your journey.
