Airlines are falling behind when it comes to keeping flights on schedule, but fewer passengers are complaining to the government.
The Department of Transportation said Tuesday that 83.5 percent of domestic flights arrived on time in November, down from 84.1 percent in October and 85.7 percent a year earlier.
Hawaiian Airlines claimed its customary spot at the top of the ratings, with 94 percent of its flights arriving within 14 minutes of schedule.
Of the 16 reporting carriers, Frontier, ExpressJet, and Southwest held down the bottom three spots; all had on-time ratings below 80 percent.
The 16 airlines canceled 5,082 flights in November, or 1 percent of their schedules.
There were 15 flights that were held on the ground longer than allowed by federal regulations. Full story for BostonGlobe.com subscribers.
