Thank you !!
Now I just need to figure out which flights have availability for GUC upgrades

Am I going to have to book, then check with Delta and if there is no availability cancel and then rebook call again, rinse repeat etc etc ?
Sorry for all these questions....never used Chase Rewards and/or GUC's
