LCC stands for Low-Cost Carrier. These are typically described as cheaper, no-frills or budget airlines. The flight types that LCCs provide are generally short haul with the majority of the bookings being made online.
By limiting the services and products they provide as standard and charging for extras, LCCs provide a cheaper type of transport compared to typical airlines. Examples of these airlines include Ryanair, EasyJet and JetBlue.
