Cathay Pacific is a Hong Kong-based international airline flying First, Business, Premium Economy and Economy class, with its own Asia Miles loyalty program and a free Hong Kong stopover option built into the booking flow. This guide covers the ways to pay less and get more out of a Cathay booking.

Check the block above, then book through our link: Cathay Pacific.

Step 1: Add a promo code at search, not checkout

The flight search form on the Cathay site has an “Add a promotion code” field right where you pick your route, dates and cabin class — enter any code there before you search, not later in the booking flow.

Step 2: Join Asia Miles before you book

Signing up for Asia Miles lets you start earning on the flight you’re about to book instead of missing out on miles from a trip taken before you joined. Asia Miles has its own tiers (Green, Silver, Gold, Diamond) plus oneworld Sapphire and Emerald status for frequent flyers.

Step 3: Add a free Hong Kong stopover

When booking a flight that routes through Hong Kong, the booking tool lets you add a stopover of 1 to 7 days at no extra fare — effectively turning one ticket into two destinations.

Step 4: Run the baggage calculator before you pack

The baggage calculator checks your allowance by route, cabin and frequent-flyer tier before you get to the airport, so you can catch an oversized or extra bag ahead of time instead of paying for it at check-in.

Other ways to save

Baggage basics

Your baggage allowance shows on your e-ticket receipt and in Manage Booking, or you can check it with the online baggage calculator by route, cabin class and frequent-flyer tier. A few things worth knowing before you pack: sharp items like nail scissors go in checked baggage, not carry-on; spare batteries have to be stored and limited per the airline’s rules; and musical instruments or sports equipment can usually be checked in for a fee, though the rules vary by route.
