What Is Regional Jet? Definition & Meaning in Aviation
A regional jet is a small jet airliner, usually seating fewer than about 100 passengers, used on shorter or thinner routes.
In plain language
Regional jets link smaller cities to hubs. Examples include Embraer E-Jets.
Example
A regional jet may serve a route that does not have enough passengers to fill a larger aircraft.
Why it matters
Regional jets connect smaller cities to hubs. Their smaller size lets airlines serve routes that would not support a larger aircraft.
