The Transportation Department said today that 79.6 percent of flights in January arrived within 14 minutes of schedule, compared with 76 percent in the same month last year.

Alaska Airlines posted the best on-time rating at 88.9 percent, while JetBlue Airways was last at 65.8 percent. Hawaiian Airlines ranked second, at 88.3 percent.

The monthly Transportation Department report has been expanded to cover 18 airlines including several smaller ones such as Allegiant Air.
