I made it back to Louisville. There was a bit of drama in Atlanta when the 45 minute connection shrunk to 25 minutes. Fortunately the gates were close -- I was in seat 32C -- and the gate agent was very, very helpful.
According to the Delta Web page, the bag is here. So I am off to pick it up.
Since everyone except Erik got sick, myself included - although I was one of the least sick, I managed to lose weight in Colombia. Hopefully I can build on that!
