Yes. Cybex lists a baseless install with the vehicle belt; see the manual for the belt routing.
Can you bring the Cybex Aton G on a plane?
Yes, Cybex lists it as certified for aircraft; look for the red-lettered label that says so. The FAA asks that a car seat go in a window seat so it doesn't block the aisle, and the crew will look for that label.
