Both Swiss and Austrian credit M&B in P class unlike any of the rest of the LH group. I don't know why and keep expecting it to be withdrawn and give nothing like LH mainline which just treats any other programme in Europe with contempt.
I treat LH with contempt in return and now never fly with them even if the fare is in a mileage earning class. I remember the day when LH boasted that they awarded miles on every ticket. There are now booking classes that don't even earn in Miles and Much, Much Less. than there used to be.
