The Cathay Pacific change flight date fee depends on your fare type and route. For most Economy Saver or Standard fares, changing your flight date typically involves a fee, which can range from USD 50 to USD 150, plus any fare difference. Economy Flex, Premium Economy, Business, and First Class tickets often offer more flexibility with lower or no change fees. You can change your flight date through the “Manage Booking” section on the Cathay Pacific website or app. If the ticket was purchased through a travel agent, you must contact them for changes. Some discounted or promotional fares may be non-changeable or come with higher fees. It’s essential to check the specific fare rules linked to your ticket before making changes. Always factor in both the change fee and any fare difference when rescheduling your travel with Cathay Pacific.
