Pax, of course, have different views as well! I would go along with the 0~4, 5~8, 8~12, 12+ as being a good guide to what regular trvaellers would consider the categories to be. An irregular pax (far too many of those
) would reckon that five hours to Lanzarote is a long haul and, in charter pitch seats it would be.
The reason I agree with the above times is that I will tolerate Y for up to 8 hours but after that I will move further forward in the a/c, even if I am paying my own way.
