Definition
A person or organization that operates aircraft to transport passengers, cargo, or mail for compensation or hire under an FAA operating certificate, in accordance with regulations such as 14 CFR Part 121 or Part 135.
Plain English
A company that is officially authorized to fly people, cargo, or mail for money. Examples include scheduled airlines and on-demand charter operators.
Context Anchor
Seen in maintenance, inspection, and operating rules that apply to aircraft used by airlines and cargo operators.
Derivation
From 'air' (the medium of flight) and 'carrier' (one who carries or transports something for others). The word 'carrier' has long been used for transport businesses on land and sea (a 'common carrier' carried goods for the public), and the same idea was carried over to aviation.
Why Pilots Care
Whether an operator is classified as an air carrier determines which regulations apply, including pilot qualifications, maintenance standards, recordkeeping, and inspection requirements. Aircraft maintained for an air carrier must meet stricter standards than those flown privately.
Intuition Check
Do not read carrier as the airplane itself. In this context, the air carrier is the person or company responsible for providing the air transportation.
Example Sentence 1
The mechanic verified that the inspection program met the requirements specified by the air carrier's approved maintenance manual.
Example Sentence 2
Mechanics at the air carrier follow a continuous airworthiness program approved by the FAA.
