Thanks enicalyth ,
I second overun's post.
I was trying to figure out why operators with low utilisation like some cargo operators that could still legally fly the 732 would want to go to a 733 citing fuel efficiency as the reason if they are only flying 5 or 6 hours a day , huge difference in acquisition and parts prices , 732 parts are getting very cheap now as there's an oversupply compared to airframes still flying.
