Cathay Pacific vs Singapore Airlines carry-on

Cathay and Singapore are near-twins for Economy at 7 kg carry-on plus one personal item. Singapore publishes a 115 cm linear sum, while Cathay only shows its size limits in its baggage calculator, so check it for oddly shaped bags. In Business, Cathay allows a single 10 kg carry-on whereas Singapore splits the allowance into two 7 kg bags within 115 cm each, so Singapore total weight is higher but per-bag weight is lower.

Cathay Economy fares use a piece allowance: Light includes 1 checked bag at 23 kg, Essential and Flex include 2 bags at 23 kg each. The second bag is therefore free on Essential and Flex only, and Cathay does not publish a flat second-bag fee for Light. Maximum size and single-bag weight limits are shown in the baggage calculator. Marco Polo Club status and oneworld Sapphire and above receive additional allowance.
