DSM to ORD was delayed, so I'd miss my 6pm to DAY. Got booked on an 8pm ORD to DAY, which was canceled 15 minutes later. Booked for next day 8am to DAY. That was canceled shortly after I got to ORD and then booked a 6pm next day. An agent this morning got me on an 11am that wasn't an option before.

Doing mandatory grant training through Workday. Any purchase under $10,000 is a "micro purchase" and a "small purchase" is between $10,000 and $250,000. Considering the size of my grant, I don't think most of this presentation applies to me.
