Booking Cathay Pacific fares as a travel agent
Travel agents book Cathay Pacific fares on IATA.co without their own IATA accreditation. Activate an agency account, top up a prepaid balance, then search live CX fares in the booking portal: the price, baggage and fare rules are shown with each offer before you confirm, and the amount is deducted from your balance. Cathay Pacific results appear whenever our flight suppliers return them for your route and dates, so what you can book follows live supplier content rather than a direct airline deal.
