A surprisingy large number of people here seem to have no or very limited knowledge of operating short haul, 737 inter-european.
Having just read the entire posted correspondence between MOL and the production company, many things jump out fro discussion.
Lets start with a very simple and straightforward one; 25 minute turnaround times.
How long does it take for a full pax load to disembark a 738?
How long does it take for a new load to come onboard, stuff away their carry on bags and sit down?
Deduct the above from the 25 minutes, how many minutes does that leave with cabin crew to do everything they are obliged to do. Obliged either by their company SOPs; clean away the rubbish not collected during the approach, tidy the aircraft and prepare the galleys for the new arrivals plus their tasks under the law like the cabin security check & the life vest check.
There simply isn't enough time.
As Sunfish so rightly says, all the manuals in the world won't help you when the company culture is not conducive.
In the case of MOL, I strongly suspect that he has all his paperwork regarding cabin SOPs in order. And when the crew are caught out not following the impossible-to-achieve SOPs, he does exactly what he is doing in this case, namely blaming the individual crew members for failing to do their task properly.
Thereby neatly circumventing having to raise his costs by allowing the crews enough time to do the things properly.
MOL knows that the underfunded and understaffed regulatory bodies wil mainly concentrate on the paperwork, and as long as that looks good they will be happy.
The odd time that his practices are shown to be faulty, he will blame his crews rather than his impossible SOPs.
Neat, clever and utterly dangerous.
