^ on this. Keep in mind that the stopover needs to be at a valid connecting city, which usually means a Delta hub such as ATL.
I am totally on page with this. I go to law school across the country, so I believe that they would get the best doing this from SAN-->ATL-->IND. May even take a place of a few flights via SW.
I think the UA card is the best bet for them. Get them out of DSM with AMEX, into a cash revolver for groceries such as the BCP (although most of their groceries are on Costco Business), and also with UA. More bang for your buck.
Thank you!
