Cathay Pacific Baggage Allowance: Checked and Cabin Bags by Fare and Cabin

Cathay Pacific moved from a weight allowance to a piece allowance when it introduced its current Economy fares, and applied the change across all cabins. A piece allowance means a number of bags, each with its own weight limit. Weight cannot be shared between bags: two 23kg pieces is not the same as one 46kg allowance.

The allowance on your e-ticket is what the airport will apply. On the e-ticket, a piece allowance usually appears with 'PC' (for example, 2PC); a weight allowance appears with 'K' or 'KG'. You can also see it in Manage Booking or with Cathay Pacific's baggage calculator.

It can differ from the general rules below when the trip includes another airline, when you hold Cathay or oneworld status, or on specific routes. If the ticket shows something unexpected, ask whoever issued it before travel rather than at the airport.

For fares, cabins and Hong Kong connections before you book, see our Cathay Pacific flights guide.

The biggest practical difference in Economy is between Light and Essential. A couple on Light fares who need a second bag each may pay more in baggage charges than the fare difference to Essential, which also includes free standard seat selection. The Cathay Pacific fare types guide compares the fares in full.

Every Economy fare includes one cabin bag of up to 7kg, according to Cathay Pacific's fare table. Travellers can usually also bring a small personal item, such as a handbag or laptop bag, that fits under the seat. Check whether the weight limit covers both items together.

Premium Economy, Business and First generally allow more cabin weight than Economy. Confirm the exact cabin allowance for the ticket, especially on itineraries with partner airlines, which may apply stricter limits on their own flights.

• Each checked piece is generally limited to 158cm in total dimensions (length + width + height).
• No single checked bag can weigh more than 32kg. Heavier items must be repacked or sent as cargo.
• Economy and Premium Economy pieces are limited to 23kg each; heavier pieces attract an overweight charge up to the 32kg maximum.
• Oversized pieces above the standard dimensions are charged separately and may need advance approval.

Sports equipment, musical instruments and mobility aids have their own rules. Check them with Cathay Pacific before travel rather than assuming they count as a standard piece.

Cathay members with higher tiers, and oneworld Sapphire and Emerald members, can receive extra checked baggage. The benefit only applies when the membership number is attached to the booking before check-in.

A child with their own seat normally receives the same allowance as an adult on the same fare. An infant travelling on a parent's lap has a smaller allowance, and a stroller or car seat may be carried separately. Confirm the infant allowance shown on the infant's ticket.

When one ticket combines Cathay Pacific with other airlines, Cathay publishes carrier rules that decide whose baggage allowance applies. For journeys to or from the United States, US Department of Transportation rules generally mean the allowance of the first airline marketing the journey applies throughout.

On separate tickets, each airline applies its own allowance, and bags may need to be collected and checked in again. A low-cost or regional airline on a separate ticket may include no checked bag at all.

Checking in and dropping bags are covered in the Cathay Pacific check-in guide.

Extra pieces can be bought in Manage Booking before travel or at the airport. Charges depend on the route and are calculated per piece, per direction. Overweight and oversized charges apply separately, so one heavy, large bag can attract both.

Before paying, compare the options. An extra piece is often better value than paying overweight charges on two existing bags, and changing to a fare with a larger allowance can sometimes cost less than both.

The Cathay Pacific Manage Booking guide explains how to buy extras on a booking.

How strict is Cathay Pacific with carry-on weight?

Pack as though your cabin bags will be weighed. We can't reliably say how often Cathay Pacific checks, and someone else getting through with an overweight bag doesn't mean you will.

Check the allowance for your cabin and membership status, including whether the weight limit covers your cabin bag and small personal item together. A laptop bag isn't automatically extra weight on top. Weigh everything at home and check the dimensions too. If you're over, sort it out before departure rather than risk repacking or having a bag checked at the airport. Keep medication, documents and valuables accessible in case that happens.

How strict is Cathay Pacific with checked bag weight?

Assume the weight limit will be enforced, and don't count on a free allowance for being slightly over. At the counter, an overweight bag can mean a charge or having to redistribute your belongings.

The most common mistake we see is treating a per-bag allowance as one combined weight allowance. If your ticket says two bags at 23kg each, you can't put 30kg in one and 16kg in the other without an overweight charge. Weigh each suitcase separately at home and leave a little room for purchases on the return trip.

If you need more baggage, check the options before departure. Adding another bag doesn't increase the permitted weight of your existing bags. For ordinary luggage, keep each bag within 32kg. Above that, paying more won't necessarily solve it; you may need to split the contents.

Will my bags be transferred automatically on a connection?

On a straightforward Cathay Pacific connection through Hong Kong on one ticket, your bags would normally be checked through to your final destination.

With partner airlines or separate tickets, check the exact arrangement. Cathay Pacific can through-check bags on some separate-ticket partner connections when the journey starts with Cathay Pacific, but don't assume the other airline offers the same arrangement in reverse.

At check-in, show all your flight details and ask: 'Where is my bag tagged to, and do I need to collect it anywhere?' Then check the destination on your baggage receipt. Take particular care with stopovers, airport changes and connections that require customs clearance. Having bags checked through on separate tickets doesn't automatically protect you if you miss the next flight.
