I'm booked on LX40 in C as ticketed by UA. Although I have the LX PNR number I'm not able to access the reservation via swiss.com. I simply get an error stating: "Your reservation status does not permit online reservation displays. In this instance, please use our Advanced Login to check-in online. (58063)".
Since my flight is not until late September, how can I see what my current seating assignment is or make changes?
