I have flown across Australia in a Citation, what a cramped aircraft. T..... if you wanted to go to the toilet.... Then you had a huge problem and would have to wait for the aircraft to land and refuel.
Exactly right! The Citation we used in Saudi Arabia had a curtained area at the rear with a funnel!Passengers often confuse the idea that a particular type of airliner is comfortable compared with another type.
It's about the airline and their decisions and choices as to the interior fit.
