Ok I am afraid of getting "enhanced" out of OP elite.. I am currently Gold going to make Platinum this year but on a mix of fares. I fly mostly NW because it is hard to justify the $$$$$$$$$$$$$$$$$$$ premium put on by CO to fly ERJ's (BTW just as a side note shouldn't they be cheaper to operate and therefore provide lower costs then the big jets? and as a result allow CO a competitive fare?)

My question is is it better to go over to UA/US (assuming comp) or try the NW switch...
AA is out as I have to many Q class tickets (friends on the west coast for long weekends)..

I also do about 3 flights a year to Asia (coach low fare and about 15 domestic mixed pricing)...

Thanks in advance for your help...
