I have about ~53K Hawaiian miles in my account. I got it through the Barclay’s card signup years ago. However since they axed me, I’ve never used HA ever since. Awardwallet had been warning me for months that my miles were expiring in June, and so I tried to buy something through their shopping portal, but it never tracked. I tried their web browsing thing, but never got it to work. I even booked an award flight and cancelled after 24 hours hoping that activity would reset it. NOPE. Today I was browsing the site and noticed I could donate miles to a charity. I called them up to ask them if that would qualify for an extension of my miles and they said yes. I double checked AwardWallet and sure enough, it’s been extended another 1.5 years. Best use of 50 miles ever.
