Ok GDK, I see what your saying. Its just that I find it unsual as its lists every single different variant, most saying "no payloads or runways limits" while others are saying for example "payload limited to 118pax as runway limits or payload/range". This may seem straight forward and chose the variants that have limited payload as it can fly the route, but where I am getting confused is that the a/c I wish to fly is the 707-320 or the 720B both meet the runway requirements and range, but still say no payload or runway limits. My interpretation of the warning means that these aircraft can't fly the route. Is this right or is the warning more a general thing that doesnt really apply? Im just not sure. Apologies if I have made things more confusing.
