From what I've read, just call AA to add notes to the record. MDW and I are taking her brother and his wife on a trip. We booked their tickets with our miles, she bought one, and I the other. Drove the cash price for our tickets way up, but we didn't see any way to ensure they both got in J with us. So I need to add 2 PNRs to our record in case of IRROPS/schedule change/AA IT/general AA strangeness.

I can’t imagine what a disaster it would be if we were separated from them. Overnight connection. They are about as infrequent flyers as can be.
