Hawaiian Airlines on Friday said it will reduce flight capacity systemwide in April and May “in response to declining demand” caused by the COVID-19 pandemic.

Flights will be cut by 8-10% in April and 15-20% in May.

Schedule changes will be introduced over the next week.

“We find ourselves in a rapidly evolving environment that has presented our company with its greatest challenge in many years,” Hawaiian Airlines President and CEO Peter Ingram said in a letter to employees. “We know this will not be our new normal, but we can’t know when health experts and community mitigation efforts will bring the spread of the virus under control — or when travel apprehension will fade.”

Ingram, according to a press release, said the company is instituting a hiring freeze and evaluating a series of actions “to reduce costs, including reviewing third-party contracts, deferring non-essential aircraft painting, and renegotiating vendor rates.”

Senior executives and board members are also voluntarily taking compensation adjustments of 10-20% effective immediately “through at least June.”

Earlier this month, Hawaii’s largest carrier announced it was temporarily suspending flights that operate between Kona International Airport and Tokyo’s Haneda Airport, and between Honolulu’s Daniel K. Inouye International Airport and HND.

It also suspended service between HNL and Incheon International Airport through April 20.
