However, as Short Haul crew, we do have to be trained on how to operate the flat beds for the occasions we operate on these aircraft. It is no different, apart from some safety aspects and equipment locations which differ between the Long and Short Haul configurations.

I also worked on a Long Haul aircraft yesterday and prefer them over the Short Haul configuration.
