As gold, I have had great success on upgrades, I do book within a week usually and do book high fares. I missed one upgrade recently IAH-ORD on a 319. This month alone, ORD-IAH, ORD-MSY twice, ORD-LAX-ORD and an ORD-SFO-ORD. Not bad, I missed one and the other was an upgraded B fare at purchase. Did 1K's leave? All this has been in the month of March
