Further to add below the paragraph starting "as for the money..."
Who knows what/how the company will think, when large numbers of Cadet SOs have upgraded and have a couple of years of P1 time on 777s and A330/350s, who perhaps don't see a long term future in the company. At this juncture, the first few batches of Cadet SOs have upgraded, but don't have a great deal of FO time yet. There aren't large swathes of newly minted FOs coming through yet. However, the recruitment bulge of 2012/2013 will see large numbers of fresh FOs come to 'marketability' in a year or so. If/when they start leaving, perhaps we can expect to see a change to our conditions. I don't see much happening in the interim - the company and the SOs know that you're not particularly marketable without a couple of years as an FO.
That hen has not yet come home to roost.
Also, my figure of $75,000 for a fresh FO didn't include the amortised 13th month. In which case it should be $80,000 (US$10,300).
