Just last month, I cleaned out the last 100K from my CO account for a Virgin UC reward. I ticketed within 15 days ($35 for being one day off

) and made one change ($35), for a total cost of $70 in CO nuisance fees. Those fees would total $225 ($150+75) if made under the new fee structure -- over three times as much.
I am glad that I got out of OnePass when I did! I am left with
exactly 382 miles in my CO account, and given the increasing costs and hassles of discretionary travel, I likely won't be adding to that total very often.
I have enjoyed being a
lowly CO Silver Elite -- it's gotten me early boarding on all flights and upgrades on a few -- but I can no longer afford status in multiple FF programs anymore. Being top-tier elite is the only way to avoid Death by Fees! It was really nice while it lasted, though.
