I book a ticket via AmEx travel (pay with points) to fly SAS from IAD-CPH. I am having the flights credited to United and they show up in my United account. However, the tickets were booked into business which shows properly on the SAS site and the seats are correct on the United site. That said, on the Untied itinerary it shows "Fare Class Premium Economy (J)." The only way that I can see this mattering is in the assignment of appropriate credit based on class of service. Is this worth breaking a sweat to deal with?
