In March 2016 Allegiant Air announced it would begin flying McDonnell Douglas MD-83s nonstop to Las Vegas McCarran International Airport and nonstop to Phoenix-Mesa Gateway Airport (IWA). The Las Vegas flight began on May 19, 2016 and the Phoenix flight several days later. The MD-83 was the largest airliner ever scheduled to Santa Rosa; as of October 19, 2016, Allegiant switched from the 166 seat MD-83 to the 155 seat Airbus A319. Allegiant ended flights to Phoenix-Mesa on January 2, 2017 and to Las Vegas on June 30, 2017 and no longer serves Santa Rosa.
