Swiss rolled out PE in March, but the TK mileage chart remains unchanged (no mention of PE, discount PE gets 0% as N). PE earns 100-135% for LH and OS. How often does TK update their mileage earning chart? My fear is that LX N will end up like LH P, forever lost in the land of zero. If TK had PE, I would be happy to give them my business. In the absence of that, is it too much to ask that they credit all of the LH group airlines equally?
