Hawaiian Airlines said today it is increasing its checked-baggage fee 70 percent for the first piece of luggage on interisland flights to $17 from $10, effective Sept. 1. All other baggage fees for travel on Hawaiian remain unchanged.

The following are exempt from the change:

Members of Hawaiian's Premier, Pualani Gold and Pualani Platinum clubs

Corporate members who book their tickets through Hawaiian's corporate portal

Customers traveling in first class

Active U.S. military personnel traveling on military or government fares

Car seats, infant carriers, or strollers when customers are traveling with a child

Wheelchairs, walkers, crutches, canes, and other personal assistive devices

Glenn Taniguchi, Hawaiian's senior vice president of marketing and sales, said the change will be the first that Hawaiian has instituted for interisland service since September 2009.

"We have changed other fees in step with the rest of the airline industry but have held the line on interisland baggage fees for the past two years," he said. "Unfortunately, increasing costs of operation make this adjustment unavoidable. Our fees for interisland service remain lower than anywhere else in our system."
