Written by If you have some Hawaiian Airlines miles sitting in your account that aren’t going to be used any time soon, you can turn those miles into Hilton HHonors points. The miles are transferred in increments of 5,000 and you’ll receive two HHonors points per mile. In other words, five thousand Hawiian Airlines miles will give you 10,000 HHonors points.
Unfortunately you can’t transfer the points online. You’ll need to contact the HawaiianMiles Service Center by email or phone. It can take up to 10-15 business days for the transfer to go through.
UPDATE 4/11/13: Read about my experience calling the service center to complete the transfer.
