A regional flight is a that tends to stay around a focus city or region. For example, a regional flight in the US would be a flight that departs from Chicago, Illinois and arrives at a destination within Illinois' or one of its surrounding states.
Although the majority of US regional flights are domestic, they can also be international if they travel across borders and the two destinations are close together. For instance, although one destination is in the US and the other in Canada, a flight from Seattle to Vancouver could be considered a regional flight. Similarly, the same could be said for a flight that departs from a southern US state and arrives at a North Mexican city.
There are a number of airlines that focus their operations on providing regional flights and can be both subsidiaries of larger airlines, or independent regional airlines. These airlines often operate on smaller, regional aircraft, and are sometimes called commuter planes.
Although there are regional airlines that fly only regional flights, a regional flight doesn't have to be operated by a regional airline. For example, the USA's biggest low-cost carrier, Southwest Airlines, flies a number of regional routes, despite also flying across the country and to international destinations.
