I need some help guys. I've been a loyal Delta flyer for the past 4 years. I don't really fly a lot to be able to get as many 800 upgrades to be sitting up front more often so I decided to switch to the airline that will give me unlimited upgrades and a little bit of more bonus miles for being Elite Member ( I think 25% is a joke ).

Anyway, I've been trying to figure out which program to choose. I'll be probably using NW most of the time ( due to schedule ) and mainly because the price difference between LIT and DFW on CO and NW is HUGE!

As far as I know there is no difference in upgrade policy and it basically doesn't matter what program I belong to and have the elite level at right ? I mean as long as I use one of them. So what do you think? Where should I start putting the miles WorldPerks or OnePass ?

Thank you guys for any help.
