Hawaiian Airlines had the nation's second best on-time record in July, according to the U.S. Department of Transportation.

Hawaiian said 83.6 percent of its planes were on time in July, which was second to Memphis, Tenn.-based regional carrier Pinnacle Airlines' 85.6 percent.

Hawaiian said its on-time record was affected by "operational issues unique to July." The state's largest airline it expects to return to industry-leading punctuality levels in August.

Hawaiian was the industry's top on-time carrier since March, replacing now-defunct Aloha Airlines, which was the industry's top on-time carrier in February.
