Hawaiian Airlines is beefing up its schedule for summer travel.

Hawaiian will operate the routes with a mix of Airbus A330 and A321neo aircraft.

“We’re encouraged by the robust demand for travel to Hawaii this summer season and these increases signal a healthy return in our key North America markets,” Brent Overbeek, senior vice president — chief revenue officer at Hawaiian Airlines, said in a statement. “We’re also excited to add a fourth HNL-LAX option, and second redeye flight, twice per week making other U.S. Mainland connections seamless and convenient.”
