Low-cost carrier

A low-cost carrier or low-cost airline (also known as no-frills, discount or budget carrier or airline, or LCC) is an airline that generally has lower fares and fewer comforts. To make up for revenue lost in decreased ticket prices, the airline may charge for extras like food, priority boarding, seat allocating, and baggage etc. Currently the world's largest low-cost carrier is Southwest Airlines, which operates in the United States and some surrounding areas.
