I was checking on two AA reward flights (between ORD and LUN) for next September.

Previously I had issues with being able to manage the trips directly on the QR website (resulting form the issue with multiple frequent flyer numbers for each passenger in the reservation as well as incomplete contact information that could not be corrected on the QR website). I had used other OW carriers to assign seats (RJ, MH, etc) and had to get QR support on twitter to assist in other changes.

I find now I have an obviously new user interface on QR's site and I can assign seats, etc.

Anyone who had experienced these issues may want to revisit this to see if their issues have been resolved as well.
