WASHINGTON — More flights are arriving on time but consumer complaints about the airlines have nearly doubled.
The U.S. Department of Transportation said Thursday that the nation's leading carriers posted an on-time rate of 80.3 percent in August. That's better than July and the previous August.
Delta Air Lines has the best on-time rate, while Spirit Airlines has the worst.
Consumers filed 1,450 complaints with the government against the airlines. That's up from 773 a year earlier. Spirit and Frontier Airlines had the highest complaint rates. Those airlines advertise low fares but charge more fees than most other carriers.
