I want to know the answer to the following question:
How many airlines operate out of Richmond International?
All the background I'm provided with is that "The Greater Richmond area is served by the Richmond International Airport (IATA: RIC, ICAO: KRIC), located in nearby Sandston, seven miles (11 km) southeast of Richmond and within an hour drive of historic Williamsburg, Virginia.". Is that enough to answer the question?
Answer: no
