Our friends at Airlineroute.net report Virgin America is dropping its twice daily service from Los Angeles International Airport to Portland on August 1.
On the same day, flights between San Francisco and Portland increase from once per day to three times daily, according to the site.
The LAX-Portland route is fairly competitive. United and Alaska both serve the route, and Delta will soon begin flights between the two cities. Also, JetBlue flies between Long Beach and Portland.
