[QUOTE=dldkjones]I'm pretty sure CO will pull any upgrade you get on CO flights using your NW FF # unless you also have elite status with CO. Might be academic though, as last year I got upgraded on CO flights as CO gold so little that I switched this year to NW.


Living in Texas I get to fly CO as much as I like.

There are loads of CO Platinums around here. The space in most of CO's

equiptment doesn't allocate as many seats as NW does in F.

As a former Gold, I was transparent to the CO EUA program.

That's why I fly NW metal.

I have been elite on DL, CO, UA, US, and AA. NW gives the best

domestic upgrades, without hassle of any US airline.
