A Ryanair Boeing 737-800 A low-cost carrier or low-cost airline (also known as a no-frills or discount carrier / airline) is an airline that offers generally low fares in exchange for eliminating many traditional passenger services. The concept originated in the United States before spreading to Europe in the early 1990s and subsequently to much of the rest of the world. The term originated within the airline industry referring to airlines with a lower operating cost structure than their competitors. While the term is often applied to any carrier with low ticket prices and limited services, regardless of their operating models, low-cost carriers should not be confused with regional airlines that operate short flights without service, or with full-service airlines offering some reduced fares.
