Thanks for all the input, I guess I will have to gamble as $700 is a bit rich for my blood, but if the stars align right and they will grant a mileage upgrade I will definatley take it. I looked at the Biz cabin for FLT 901 on the 23rd and it looks pretty barren while I cannot choose a seat yet for my flight, anyone know why UA does this? I usually fly AA but this year I am doing some long haul on AC (I was able to pick my seats for my HKG trip in Oct) so I am using UA to build status this year with them and try them out and see if the switch is worth it.
