A recent experience has convinced me that the whole BACON thing is not sustainable.
I recently flew Manchester - Frankfurt return in C Class both ways.
On the outbound leg, I flew on a EMB145 with a total of 14 passengers on board (including me). The flight although quite pleasant, arrived rather late, for no apparent reason, just late.
On the return leg I flew in a LH A321 - a proper plane - sorry but it is IMHO.
The back end was near as damn it full and there were 23 passengers in the C Class cabin which is considerably more than the entire uplift of the BACON flight. On top of that, the experience was a true pleasure (but why always cheese with everything LH?) and we arrived exactly on schedule.
People do tend to vote with their feet.
