I wish I had opened up my pnr in this search tool before making an utterly infuriating call to MP support center just now. With hold times what they are these days, HUCA is not an appealing option, unfortunately, but I was just about at that point with this particular agent. Lesson learned... So,I thought I'd provide another data point on the potentially invaluable utility of the extra information (that I now have open, and wish I had at my disposal 5 minutes earlier!).

Backstory:

HNL-GUM, 4JUN. On 11 May, my uncle sponsored u/g using 20 pluspoints. I was u/g'd to PP day before travel
GUM-NRT, 9JUN. On 28 May I requested ug using 7,500 of my own miles. Ug did not clear.
As of today, 20 Jun, there is still no refund of the miles, so I called MP Service Center for what I thought should be a very simple refund.

Unfortunately, agent became fixated on 4JUN and kept saying "you were upgraded, there is no refund". Over and over I explained the 7,500 mile upgrade was for GUM-NRT on the 9th, and she kept saying, "Our records do not show that. They show you used 7,500 miles to upgrade your flight from HNL to GUM, which cleared so no refund is due".

Me: HNL to GUM upgrades are not even 7,500 miles, how does that make any sense?!
Agent: Well sir, that is confusing.
Me: The HNL to GUM upgrade was a pluspoint upgrade sponsored by my uncle
Agent: Sir, there is no record of any pluspoints. (after searching) the last time you used your plus points was in 2021
Me: Again, these were from my uncle's account. Would you like that number?

After pulling up his account, she FINALLY realized she was wrong.

So after all this frustration, IF I had looked at the notes, the information IS CLEARLY available (futher highlighting the utter incompetence of this agent). I could have just said, "Please see lines 17-21 for the 7,500 miles deducted for GUM to NRL"

All that said, is an upgrade award chart still published anywhere??? (I know the award travel charts are gone now, but AFAIK, MP ugrades are not dynamically priced). I wanted to challenge the agent to tell me the cost of a HNL-GUM upgrade to prove that it could not have been 7,500, but I did not know what the correct amount is for that route.
