I presume those saying that pax aren't bothered if a Helvetic F100 turns up instead of a LX Airbus are flying in Y and not J. The F100's are quite a step down from the LX metal and to say Helvetic crew are as good as Swiss crew also mystifies me. Granted it's only a short hop, but there is a world of difference between the two. I do the route regularly.
I agree with the comment about the competitive J fares on LX ex-MAN having disappeared. I am afraid this happened shortly after LH announced they were dropping some of their cheaper short haul J fares. I've started having to fly BA more....
