Weight Concept
On flights not serving the United States or Canada (or other locations specified by the airline where the Piece Concept does not apply), passenger baggage is controlled by the so-called Weight Concept. Under the Weight Concept, each passenger is permitted to check a total bag weight in however many bags they have. Typically, Economy Class is permitted to check in up to 20 kilograms, Business Class is permitted to check in 30 kilograms, and First Class is permitted 40 kilograms. Some Airlines mainly based in the Middle East such as Emirates, Gulf Air, Qatar Airways, Etihad Airways, etc. offer 10kg extra per class, so 30kg Economy, 40kg Business and 50kg in First Class. Unlike the Piece Concept, in which weight restrictions are per bag, the Weight Concept allows passengers to combine their bag weight into fewer bags which would otherwise be too heavy to travel under the Piece Concept.

Famous quotes containing the words weight and/or concept:
“I ascribe a basic importance to the phenomenon of language.... To speak means to be in a position to use a certain syntax, to grasp the morphology of this or that language, but it means above all to assume a culture, to support the weight of a civilization.”
—Frantz Fanon (1925–1961)
“It is impossible to dissociate language from science or science from language, because every natural science always involves three things: the sequence of phenomena on which the science is based; the abstract concepts which call these phenomena to mind; and the words in which the concepts are expressed. To call forth a concept, a word is needed; to portray a phenomenon, a concept is needed. All three mirror one and the same reality.”
—Antoine Lavoisier (1743–1794)
