Delta DID catch it and called him to make a decision on which he would be using. They have made some major strides in tracking these things.
Hmm. I'd actually be okay if they caught it and called me in advance. I just don't want my new ex-SLC ticket to be cancelled silently, which is what AA seems to do when they notice duplicates. (Or, worse, have the whole original JFK->SLC->JFK for two of us cancelled.)
In any case, went ahead and booked a new itinerary; will hope there are no problems waiting til I arrive in SLC to change the original ticket.
