Virgin America is increasing service between Portland in Oregon and San Francisco and ending direct flights between Portland and Los Angeles.
On 31 July, the airline will discontinue its two daily nonstop flights between Portland International airport and Los Angeles, according to Virgin's website.
The following day, Virgin will add two additional daily frequencies between Portland and San Francisco, bringing its number of daily roundtrip flights between the cities to three.
The airline will continue to serve the Portland-Los Angeles market with connections through San Francisco.
Burlingame, California-based Virgin tells Flightglobal that Portland, which the airline has served for roughly one year, has been a "great market" that "matches well with the Virgin America brand".
Virgin adds, "We think we can achieve even bigger things in this important West Coast market with this schedule adjustment, which will significantly increase the number of efficient connecting flights between [Portland] and destinations across the rest of the Virgin America network."
