Island Air said Wednesday that 85.9 percent of its flights arrived on time in December and that it completed 99.6 percent of its 1,054 flights that month. There were four cancellations.

For the year, Island Air’s on-time-performance averaged 88 percent, an improvement over 2015 when 82 percent of its flights arrived on time. A flight is regarded as on time if it arrives within 15 minutes of its scheduled arrival time, according to the U.S. Department of Transportation. Island Air completed 99 percent of its flights during the year.

“The entire Island Air team is extremely proud of the improvements we achieved in our overall operational performance in 2016,” Island Air President and CEO David Uchiyama said in a statement. “As we convert our aircraft fleet to new Q400 turboprops over the next few months, we will continue to focus on providing a safe, reliable and superior travel experience for our passengers on every Island Air flight.”

HECO wants to offer medical discounts

Hawaiian Electric Co. said Wednesday the electric utility and it’s sister companies on Maui and Hawaii island plan to offer a discounted rate for customers with special medical needs.

HECO has asked the state Public Utilities Commission to approve the plan to start April 1. The company said up to 2,000 customers who are dependent on life support equipment or increased heating and cooling because of a medical condition would qualify to save up to $20 a month on the first 500 kilowatt-hours of energy use on their monthly electric bill. If those in the program use more than 500 kWh, they will be charged regular residential rates. Applications will be available online and require a licensed physician’s signature.
