Cathay Pacific — flights, check-in & baggage guide

Cathay Pacific (IATA code CX) is a full-service carrier from Hong Kong operating out of Hong Kong International Airport.

Founded in 1946, it is a member of oneworld and part of 太古集团.

Cathay Pacific, a oneworld stalwart, connects five continents through its Hong Kong super-hub and consistently ranks among the world’s best airlines — its HKIA lounges (The Pier, The Wing) are considered world-class. Transiting HKG often beats nonstop options on price and product.

This page gathers the essentials for flying with Cathay Pacific: official website, fares, online check-in, baggage rules and customer service contacts.

Since its founding in 1946, Cathay Pacific has grown into a significant force in the Hong Kong market with the backing of 太古集团. As a oneworld member, its frequent flyers earn and burn miles across the global alliance network.

The network is strongest across Five continents via the Hong Kong super-hub. Departing from Hong Kong International Airport gets you the best frequencies, timings and irregular-ops backup; from non-base cities expect more one-stops, so watch total journey time when booking.

Booking tips: fares float with live inventory — 2–6 weeks out (2–4 months long-haul) is usually the trough, and member pricing can undercut platforms. Add your Cathay (formerly Asia Miles) number at booking; retro-crediting needs boarding passes. Paid upgrade windows open around check-in at prices well below purchase-time premiums, and pre-bought extra baggage saves 30%+ versus airport rates.
