Airlines canceled and delayed fewer flights in March and consumer complaints were down.
The Department of Transportation said Monday that 81.5 percent of flights on the main airlines arrived on time during March, up from 78.7 percent in March 2015. Hawaiian Airlines was the best performer, while Spirit Airlines finished last.
About 1 percent of flights were canceled during the month, an improvement from 2.2 percent a year earlier.
The figures don’t include more recent periods, in which thousands of passengers have missed their flights because they were stuck in long security-checkpoint lines.
The report covers the 12 largest U.S. airlines.
Flights on Hawaiian, which routinely operate in good weather, arrived on time 89.9 percent of the time. Delta Air Lines was second-best at 87.9 percent.
