In setting up my LONE3, I have a number of connections where I am not planning on actually stopping (e.g. DPS-HKG-BOM).

Would the taxes and airport fees be less if I had them ticket these as connections (Xs) rather than destinations (Os)? What if it's one of those long layovers (either all day or overnight) where it can be ticketed as an X but I would leave the airport?

Thanks!
