The SDC options you are currently presented for an AAA-BBB flight are now pretty much the same as the options that you would be presented if you tried to do an AAA-BBB booking. A few options don't seem to show up, but those appear to be mainly broken fare options.

The LAX-SYD options make sense though because internationals seem to be a little more liberal.
