Guy has a Masters degree and yet can't figure out how to buy a magazine subscription to keep his miles from disappearing.
Indeed. I just reset the clock on my Southwest miles by transferring 1,000 UR points
from my Chase Ink+ card. Now they're safe through August 2018.
All airline miles expire from non-use, so I keep a spreadsheet for tracking. I also
keep track of my Hilton points, and keep them alive by making 1-2 small purchases
each year on my Hilton Amex card.
AwardWallet.com will track most of your travel points, though ironically not
Southwest.
