Hawaiian Airlines is adding capacity to both Oakland and San Jose, California, from May, citing strong demand.
The carrier will add a daily nonstop flight between its Honolulu International base and San Jose International on a 264-seat Boeing 767-300ER from 16 May, and replace a 767 with a 294-seat Airbus A330-200 on its nonstop flight between Honolulu and Oakland International from 18 June, it says.
Hawaiian has flown Honolulu-San Jose sporadically in the past.
On 12 March, the airline moved up the start date of its planned Los Angeles-Kahului flight to May and announced plans for a second daily flight from June to September.
Strong demand was cited for the additional capacity on the Los Angeles route as well.
However, Hawaiian is ending service to Taipei in April and Fukuoka in June, leaving it with free aircraft as it comes into the busy North American summer travel season.
These aircraft could be partially behind the increases in capacity to Los Angeles, Oakland and San Jose.
Hawaiian competes with Alaska Airlines on both the Honolulu-Oakland and Honolulu-San Jose routes, Innovata schedules show.
