Seems you have gotten sucked in by the smoke n mirrors. A cursory glance reveals that the standard 6/2 package is still $10.8 per month (circa 2008) all the other variations have always been available with crew rostering, but the money hasn't improved. They are selling you a 6 for a 9.
Oh and the 330 is less than 1k better than the 320...:
Nothing new here mate!
Would love to know which agency has sunk to this deceptive recruitment method.. Do tell
(See my post April 14, nobody is getting 4/4, 4/3, 5/4 the rest are just variations IE 6/3 $9.4K same as 4/2, 4/1 $11.6K same as 8/2, guys have negotiated these sort of rosters for years, but all predicated around the base 6/2 salary)
