You can bring one free piece of luggage as your carry-on along with one small purse, backpack, briefcase, or laptop free of charge. The Cathay Pacific baggage weight restrictions for carry-ons are determined by your cabin class. And if you are flying with a musical instrument, it can count as your one carry-on item as long as it adheres to the airline's small musical instrument size limitations.
The Cathay Pacific checked baggage allowance is determined by your route, cabin class, and member tier, but all passengers are granted at least one free checked bag. However, you may incur Cathay Pacific baggage fees if you have additional luggage or if your bags exceed the airline's maximum size and weight restrictions.
