Brad Tilden assumed the position of chief executive at Seattle-based Alaska Air Group today.
He succeeds Bill Ayer who announced his retirement in February.
"Brad has a proven record of success spanning two decades at Alaska and we've worked side by side to fundamentally transform our company as the industry has evolved in recent years," says Ayer in a statement. "I have complete confidence that his leadership style, strong values and seasoned judgment will continue our success."
Tilden remains president of Alaska Airlines. He has worked as chief financial officer and executive vice president of planning and finance at the group since joining in 1991.
The group owns Alaska and Horizon Air, which together comprise the seventh largest airline in the US with hubs in Anchorage, Los Angeles, Portland and Seattle.
