So, can not book award ticket because I am missing 20K miles. CSR still said there is nothing they can do.
This is't a glitch--it's a deliberate action on UA's part. Because UA screwed up and had awarded some pax miles based on incorrect criteria, they're removing
all promo miles from
all participant's accounts, with the promise that they will "correct" things in a couple of days.
See
UA Removing Already-Posted Bonus Miles for "Map Your Dreams".
You can probably expect the miles to show up again within a couple of days--assuming UA gets things "right" this time (

). Of course, the T&C of the offer say they have many weeks after 7/15 to credit the miles, so it could be you won't seen them until almost October, and you may have to fight for them even then.

Yes. It's something else I need to add to spreadsheets to keep track of.
