I recently had 10mins between FRA-MUC and MUC-GRU, due to inbound being late. No help from LH. No one at the gate helping. And this in C. You need to go all the way back to the central concourse, then up to passport control jumping the cue on two hundred other pax and then a couple of conveyour belts back to H28. I was the only one who made it out of a bunch of 15 pax. Lousy service on behalf of LH. But lot's of empty seats in C that morning on the MUC-GRU... plus me clutching to my asthma spray as we climbed past the beautiful alps. Could not have done it at different age (am 37) or with family and kids.
