Comfort seat booking is legal, and its the best way to do it.
As I mentioned, have to phone them up.
I would not do the booking of 2 seats in 2 names, (one yours and one made up), and if one does not show up, there is a chance of a no show, and you loose the 2nd seats, ie the whole booking.
If on the same PNR, the whole booking can be cancelled.
If you book in 2 PNR, that 2nd seat might be issued to someone else, as BP are always scanned at the gate.
Do it the legal way.
I think its illegal to fly in a ficticious name, some how the govt always seems to know when bikies make bookings for flights in false names and they get caught.
Comfort seat booking is twice the seat costs, but only 1 set of flight taxes.
Edit: as others have said, comfort seat booking and econX are completely separate things on a flight booking.

****My guess is that it would be priced per the cheapest economy fare. You earn points, no sectors or status credits.****
You will earn 2 sets of VFF points, 1 set of sector, and 2 sets of VFF SC for a comfort seat booking, have done it several times.
Made QFF SG once this way, and VFF PS.
If you shop at Coles all the time, you can also still earn VFF SC that way, and VFF points too.
There is a way to guesstimate the fare calculation for comfort seat booking, try to find the basic fare, take away the taxes, double the fare without taxes, and then add the tax back.
VAd discJ fares are so cheap now, that its a better idea just to book a discounted J fare, rather than faffing around, if you book far ahead of time of flight.
ADL - MEL discJ $299, if you book ahead, it even gives lounge access.

Not sure if this has been legislated, or if it passed fed parliament, or did it lapse...
