A commuter airline refers to a small-scale airline that operates short flights primarily between nearby towns and cities. These airlines offer affordable air travel options for people commuting for business or personal reasons. Synonyms for the term include regional airlines, feeder airlines, short-haul airlines, and shuttle airlines. Regional airlines connote flying within a certain region, while feeder airlines suggest connecting flights to major airlines. Short-haul airlines denote short-distance flights, while shuttle airlines imply a high frequency of flights between two destinations.
