Virgin America will begin non-stop daily service to San Francisco from Denver on March 15.

Virgin will fly Airbus A320 aircraft with 149 seats and three classes of service. The airline will fly from the A concourse. Virgin’s ticket counter will be on the east side, near competitor Frontier.

According to Denver International Airport, Denver is the largest market that Virgin America doesn’t already serve from San Francisco and is the top destination requested by the airline’s high-tech corporate accounts. DIA said about 860,000 fly between Denver and San Francisco each year.

“We’re looking forward to bringing a breath of fresh airline competition to this important market and to building strong community ties with the city of Denver and state of Colorado,” said Virgin America president and CEO David Cush.

Prices will range from $129 for coach seats to $399 for first class.

To launch the new service, Virgin is offering $52.80 fares from Denver to San Francisco on certain days between April 5 and May 24.
