The Department of Transportation said Tuesday that only 80.2 percent of flights in October arrived on time. That was worse than 83.3 percent in September and 85.5 percent in October 2011.
American Airlines had the worst on-time record for the second straight month, while Hawaiian Airlines held on to its usual perch on top of the government rankings.
The airlines canceled 2.8 percent of their domestic flights, nearly four times as many as September and October 2011.
Sandy caused more than 12,000 cancellations — 83 percent of all canceled flights for the month.
