I have seen this repeated here many times. I'm booked in J on AF65 LAX-CDG in June, and currently have seats 60K/L. I booked the flight using DL miles, but selected the seats on airfrance.us after obtaining the AF reference number from a Delta phone rep. Is this one of the situations that sometimes results in the seat assignment being "lost"? I'd really prefer not to lose those seats, since they are considered by many to be the best J seats on the 388.
