I'm in the process of booking flights to Europe, for the first time without the nonstop into FRA. Not only is it quite inconvenient to fly US through PHL, it is much more expensvie since I need a connection out of FRA to reach my final destination.
If Lufthansa re-establishes the Bayer Express..........I'll keep my FF allegiance with *A. Of course this may be UA versus US.
