US says airlines are improving at on-time performance

Airlines are doing a better job of sticking to their schedules, and consumer complaints are falling.

The Department of Transportation said Monday that 84.5 percent of flights on the largest 12 U.S. airlines arrived on time during April, better than the previous month and up from 81.8 percent in April 2015.

Hawaiian Airlines and Delta Air Lines were the best at staying on schedule, while Spirit Airlines was last, arriving late more than one-fourth of the time.

Consumer complaints about U.S. airlines fell to 870 from 1,083 in April 2015.
