How Airline Baggage Allowance Works: Weight vs. Piece Concept

How Airline Baggage Allowance Works: Weight vs. Piece Concept
Unexpected airport baggage penalties can ruin an otherwise affordable trip. Airlines worldwide enforce two primary baggage systems: the Weight Concept and the Piece Concept.

The Weight Concept (Standard in Asia & Middle East)

Under the weight concept, your ticket grants a total weight allowance (e.g., 20kg, 30kg, or 40kg) that can typically be distributed across one or more bags, provided no single bag exceeds 32kg for baggage handler safety.

The Piece Concept (Standard for North America & Select African/European Routes)

Under the piece concept, your ticket specifies a precise number of checked bags, each with a strict maximum weight (typically 2 pieces of 23kg each for Economy Class). Exceeding 23kg on a single bag triggers an overweight fee, even if your second bag weighs only 10kg.
