Low-cost carrier

A low-cost carrier (LCC) or low-cost airline, also called a budget, or discount carrier or airline, is an airline that is operated with an emphasis on minimizing operating costs. It sacrifices certain traditional airline luxuries for cheaper fares. To make up for revenue lost in decreased ticket prices, the airline may charge extra fees, such as for carry-on baggage.

The term originated within the airline industry referring to airlines with a lower operating cost structure than their competitors. 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-haul flights without service, or with full-service airlines offering some reduced fares.

Some airlines advertise themselves as low-cost while maintaining products usually associated with traditional mainline carriers’ services. These products include preferred or assigned seating, catering, differentiated premium cabins, satellite or ground-based Wi-Fi internet, and in-flight audio and video entertainment. The term ultra low-cost carrier (ULCC) has been used, particularly in North America and Europe to refer to carriers that do not provide these services and amenities.
