Cathay Pacific typically offers Business and Economy cabins (with First or Premium Economy on some widebody/long-haul routes). Cabins differ notably in seating, catering, baggage allowance and mileage accrual.
For short routes economy is usually the best value; on overnight or long-haul flights Business meaningfully improves rest. Watch for upgrade offers with miles or cash around check-in time.
Product-wise: 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.
On loyalty: Cathay (formerly Asia Miles) members accrue miles by cabin, and elite tiers add seat, baggage and lounge benefits — worth joining if you fly Cathay Pacific often.
