Definition
A category of commercial operator certificated to conduct on-demand passenger or cargo flights for hire, typically in small aircraft, under the regulatory framework that governs air taxi and commuter operations (14 CFR Part 135).
Plain English
A small commercial flight company that's licensed to fly people or cargo for money on short-notice, point-to-point trips, rather than running a fixed airline schedule.
Context Anchor
Seen in FAA acronym lists, operating rules, and documents that refer to air taxi operators.
Derivation
‘Air taxi’ borrows from the idea of a ground taxi: a vehicle hired on demand to take you where you want to go, rather than following a fixed route. Add ‘commercial operator’ and you have a business licensed to do that in the air.
Why Pilots Care
Pilots flying for these operators must meet specific training, duty-time, and aircraft-maintenance standards that differ from scheduled airlines.
Intuition Check
“Air taxi” does not mean an airplane taxiing on the ground. Here it means a paid aircraft service arranged to carry passengers or cargo.
Example Sentence 1

Example Sentence 2
