In the interest of full disclosure, I must note that the agent actually called me back and finished the transaction. It was domestic so she probably didn't have access to KE availability, but I was so thrilled that she called back that I forgot to ask.

At least I don't have to go to the DO via LAS now. I found a DL redeye from SAN to IAH and ponied up the extra 25,000 miles for an easypass return on CO metal that still allows me to attend the brunch. I was able to cancel my WN positioning flight and use those funds for my wife's flight to PHX in April. All in all, a good travel day from a strategic point of view.
