NEW YORK (AP) — Airlines are struggling this year to get planes to the gate on time.

U.S. carriers in January and February only saw 80.3 percent of their flights arrive on time, the government reported Thursday. That's down from a record 84.9 percent during last year's storm-free winter.

Mother Nature hasn't been as cooperative. The percent of flights canceled this February doubled to 2.4 percent from 1.2 percent in the same month in 2012.

As for airports, Phoenix had the best on-time departure and arrival rates in February while Chicago's O'Hare International Airport had the lowest. A flight is still considered on time if it arrives within 15 minutes of its scheduled time.
