Ok, got all of this out of the brochure dealing with the FF program - so who knows, the brochure *may* be wrong.

According to the brochure, MEL-SIN is 3749 miles. SIN-LON is 6758 miles. This adds up to 10507 miles.

But according to the brochure, MEL-LON is 10518 miles. These are Great Circle distances, which is the absolute shortest distance between two points.

So how can the absolute shortest distance between MEL and LON be MORE than the sum of two sectors? By definition, it can't be.

ANy thoughts?
