I can definitely confirm that it works, actually quite well and consistent ^

I also agree that too many LH employees either drunk the cool blue aid or lack the competence to have a more substantial opinion, so comments like " We will never cancel a flight for commercial reasons " ( I have that one in black and white on paper ! ) or " the last flights of the day will not be overbooked " are an every day scenario that ( unfortunately ) too many people take for granted...

Not to mention that " long haul planes never get a bus gate at FRA..."
