Air carrier

An air carrier is a company that provides commercial transportation services using airplanes. These companies operate scheduled or charter flights carrying passengers, cargo, and/or mail. They can fly domestically within a country or internationally between countries.

There are two main types of air carriers. Full-service carriers (FSCs) typically have ancillaries like in-flight meals or seat allocation included in the ticket fare and often target a broader range of passengers, including business travelers. 

In contrast, low-cost carriers (LCCs) offer fewer amenities and usually charge extra for services like checked baggage, seat selection, and onboard meals. With a main focus on providing lower fares, LCCs often run shorter, point-to-point routes and use secondary airports, allowing for simplified operations and cost savings.

To provide their services, air carriers must obtain corresponding certifications and licenses from national regulators such as the US Federal Aviation Administration, UK Civil Aviation Authority, Ministry of Transportation of Japan, etc.
