I could use some experienced input please. I'm a newbie to this forum.

I've recently moved from the Northeast to the NorthWest, and have taken a job where I will once again, be traveling 100K or more a year. I had my favorite FF Programs from back east, but now need to pick a new one to concentrate on because of the different starting point(SEA) in my travel patterns.

What I'm after is the best upgrade success percentages & bennies, and the coach seating comforts while I'm getting to the elite status levels (again). I have more than 1,000,000 miles stashed away from prior road warrior days, and accruing miles isn't a priority.

Anticipated destinations are pretty much anywhere US (major cities), with an occasional jaunt to Europe.

My poking around indicates that...

1. Alaska looks interesting, because of the AA and NW partner accruals towards status, but partner flights accrue at a diminished %. They also list the most clubroom partners.

2. American looks promising, but I have no experience with their elite levels.

3. United with their E+ looks good, but my experience with them is that until you reach platinum, plan on spending all your time in coach.

4. CO (my prior favorite back east)has limited coverage out here, so they're out.

Any advise and input would be greatly appreciated.
