Cathay Pacific (CX) Baggage Allowance Calculator

For Cathay Pacific flights, your carry-on must measure at most 56×36×23 cm and weigh no more than 7 kg — the sizer at the gate is the arbiter, not the check-in agent. Bags over 7 kg must be checked on Cathay Pacific; airport scales are accurate and staff enforce the 7 kg limit strictly.

A small personal item (purse, small backpack, laptop bag) is also permitted on Cathay Pacific provided it fits under the seat in front of you.

The checked allowance on Cathay Pacific is 23 kg per standard bag — bag-inclusive fares are one of this carrier's quiet value levers. The linear dimension limit (L+W+H) on Cathay Pacific checked bags is 158 cm.

Each additional bag beyond the first runs $60 USD pre-booked online. Overweight charges on Cathay Pacific start above 23 kg at $10 USD per kg; items between 23 and 33 kg typically incur a flat surcharge instead.

Excess pricing on Cathay Pacific (CX): $60 per extra bag, $10/kg over 23 kg — the calculator multiplies both for your group. Compare strategies before paying: a second 18 kg bag at $60 often beats $10/kg overweight on one heavy case — the calculator tests both configurations for Cathay Pacific (CX).

Repack before you pay: splitting weight across two bags at $60 each frequently undercuts overweight fees on Cathay Pacific, and online pre-booking undercuts the counter by 40–60%.

Sports gear on Cathay Pacific (CX) travels as standard checked baggage within the weight allowance at no extra cost. Instruments under 8 kg and within carry-on dimensions may travel in the Cathay Pacific cabin; larger instruments need either a bought seat or checked handling — Cathay Pacific recommends hard-shell cases and a declaration at check-in.

Assistive devices are always free on Cathay Pacific (CX): wheelchairs, scooters and walkers are accepted at the gate and returned aircraft-side wherever feasible.
