Definition
An air carrier that operates flights on demand or by special arrangement rather than according to a published timetable. Nonscheduled airlines typically conduct charter, cargo, or supplemental passenger operations and are certificated under specific regulatory provisions that distinguish them from scheduled commercial carriers.
Plain English
An airline that flies when customers hire it to, not on a fixed daily schedule. Trips are arranged on request, often as charters or one-off cargo runs.
Context Anchor
Seen in discussions of charter flying, on-demand passenger service, and the difference between regular airline service and arranged air transportation.
Derivation
The everyday word 'schedule' comes from the Latin schedula, meaning 'a small piece of paper' — originally a written list of times. A nonscheduled airline simply means one that does not operate from such a published list of departure times.
Why Pilots Care
Determines which FAA operating rules and certification standards apply to the flight.
Intuition Check
Do not read nonscheduled as “unplanned” or “disorganized.” It means the airline is not flying that service as part of a regular published timetable.
Example Sentence 1
The freight company hired a nonscheduled airline to move urgent cargo to a remote mining site over the weekend.
Example Sentence 2
Nonscheduled airlines often serve niche markets where fixed schedules would not be profitable.
