Alaska Air Group's two airlines, Alaska Airlines and regional carriers Horizon Air, both achieved on-time arrival rates of more than 90 percent in April, the airline holding company reported to the federal Department of Transportation this week.
Alaska and Horizon have been among the nation's most punctual airlines for the last several years after they adopted a new countdown system that keeps plane servicers and ramp workers updated on the planes' scheduled departure time.
The two airlines, based in SeaTac, also reported gains in passenger traffic last month, 4.3 percent for Alaska and 2.9 percent for Horizon. Those increases in the number of passengers matched exactly the two airlines' increase in capacity.
That increase in both usage and capacity resulted in planes that operated with the same percentage of seats filled as in April 2013. For Alaska, that percentage was 86.8 full and for Horizon 78.3 percent full.
Horizon now operates all of its flights under the Alaska brand name though it remains a separate company with separate contracts with its employees.
