Womp, whomp. Semi fail on using my Hilton quarterly credits that my buddies here can appreciate.
We booked a local Hilton for one night to escape the heat dome our A/Cs absolutely cannot handle. (Worked perfectly, they had the room set to artic and it was a comfortable cool sleep!)
I have a number of credits to use between our Biz Plats, and Hilton cards in 2P mode. So I asked to split the charge 50 on Biz Plat, 50 on a Surpass and the remainder on my Biz. Had to wait for the gentleman who knew how to properly split, but he was very pleasant and agreeable!
Card one goes in - Declined! And again on take 2.

Well maybe fraud alert or something, haven't used this one in person in a while, put in Card two and Success!
Ok check app, not frozen, no texts, no alerts, no emails. Let's try take 3 - declined again!
I was on a clock so didn't have time to further look into it, so at least 2 credits will get used up.
I thought AmEx had a super simple way to avoid charges that are only using up the Biz Plat credit - just decline anything $50 even!
On further reflection, I grabbed the old,
cancelled Biz Plat.

Insult to injury, the new active card was in my purse and in my digital wallet! If I'd have noticed the very subtle sequential digit change, I could have whipped out the correct card and happy ending. I was even in my digital wallet looking for the card in case there was something wrong with the chip, and when the digits didn't match up no alarm bells went off. If only I'd have given the card a try from my phone anyway
Oh well, lesson learned, guess I can live a little on the next attempt since I have another $50 to use up!
