Correct, though they won't show a RT using different airports for departure and arrival, CMIIW.
Well, technically that's not a RT.
It's unclear to me what "using different airports for departure and arrival" means. If it means I fly from my city's only airport to LGA, then return from JFK to my city, I'd consider it an open-jaw RT.
Don't book domestic as roundtrip. Search and book as one ways.
Why do you say so ?
It's cheaper usually
it's good to be a Lubavitcher
-1, ime. If one ways are cheaper, it will price out with 2 one ways anyway.
Not always if separate carriers.
