Island Air said today that 85.9 percent of its flights arrived on time in December and that it completed 99.6 percent of its 1,054 flights during the 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 “on time” if it arrives in less than 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.”
