Hawaiian Airlines, seeking to encourage more passengers to become frequent fliers, is raising its fees for non-HawaiianMiles members on interisland routes from 47 percent to more than double for checked bags.

Non-HawaiianMiles members will see their fees increased to $25, from $17, on a first checked bag and more than double to $35, from $17, on a second checked bag.

The changes will be in effect for tickets purchased on or after March 10, Hawaiian said Friday.
