Ron beat me to it, but the ways that come to mind are either just spend more cash on the cards, do a paid flight or transfer points in from Hyatt or Marriott. IIRC loss from UR through Hyatt is less than Marriott if you wanted to go that way. I looked at the MMS link and the Choice approach isn't bad either. Amazing how many paths to arbitrage there are.
I tried to talk a sister-in-law into chasing the companion pass since she transports herself and daughter out to see her ex several times a year, but she wouldn't go for it because the flight times weren't quite right (valid reason). She would have gotten massive $$ out of that.
