NEW YORK (AP) -- Better weather is helping airlines get passengers to their destinations on time more often, but the summer travel rush slowed them down a bit in June.
The Department of Transportation said Thursday that four out of five flights in June arrived within 15 minutes of scheduled times, giving the nation's largest airlines an on-time arrival rate of 80.7 percent. That's up from June 2011's 76.9 percent rate but down from 83.4 percent in May 2012.
Hawaiian and Alaska Airlines once again held the top spots. US Airways Group Inc. had a higher on-time rate than any other network airline. United Airlines was in last place.
There were no delays of more than three hours for a domestic flight. There was one international flight that sat on the tarmac for more than four hours.
DOT said fewer delays, and a lower rate of lost or damaged bags from last year, means a busy air traffic system is getting more efficient. There also are fewer flights now than a year ago.
