Southwest Airlines says it will end its twice-daily flights between Reno and Oakland, Calif., in June.

Officials at Reno-Tahoe Airport say the move is in reaction to challenging economic times and the ability to fill seats on short flights. For many people, flying is a luxury when it takes only four hours to drive between the two cities.

A Southwest spokesman tells the Reno Gazette-Journal that air service nationally is trending way from shorter flights.

On average, seats on Southwest's Reno-Oakland flights were 55 percent filled.

Southwest is Reno-Tahoe International's main carrier, accounting for a little more than half of all passenger air travel to the region.

Alaska Airlines operates two daily flights between Reno and San Jose, and United Airlines has three daily flights connecting Reno with San Francisco.
