I think your right it will almost certainly come to crews refusing to do it or going fatigued down route, and probably being threatened with the sack.
The schedule is such that u get to the hotel in the morning and check out in the evening, its noisy and impossible to get proper rest.
In light of the very real claims made about fatgue recently in the media, when will people wake up and listen. I wonder how happy the pax would be if they knew this information?
would be nice to hear from gsm crews about this.
