Due to the decreasing attractiveness of US as a *A member I am considering switching to UA. I have AAirpass with AA and like it very well but there are many times when I need different options. From the website it appears that LH and LX can also be booked with PassPlus. That would dramatically increase the utility to me. Does anybody know about the benefits of PassPlus in terms of GS etc? Is the international pricing advantageous when compared with typical purchased premium fares? Does customer service work well? How about trip changes? FWIW, all my travel is LH international. I very, very rarely fly domestic US. I may be missing other important questions, if so please tell me. My past experience tells me the actual experience with such programs sometimes differs materially from that describes on the website; sometimes better, sometimes not.
