Although I was Pualani Platinum for two years and found it easy to use accrued points on Hawaiian, I never once was able to use the upgrade certificates issued in spite of many attempts. I did raise the issue with the airline but it went nowhere other than creating a bit of noise. It was obvious that the routes I typically flew were too busy and booked and there was never a chance to use my certificates. So, as part of an overall disappointment (I had a couple of trips HNL-SYD in Business/First where I had a faulty tray or seat and a few clapped out planes) I gave up, used my points and will never fly them again. I wonder if others have had these experiences of apparently - in spite of the hype and smoke and mirrors - not being appreciated?
