Compared to most folks here I am "not worthy", but I did fly about 35segments (but split on too many airlines) in one 12 month period spanning 2006/07 so I'm not an "infrequent flyer" either.

Here's the deal -- In 2007 I flew:

US - ~5000 miles and got Silver based on a Challenge which expires Feb 08.
CO - ~9500 miles
NW - ~500 miles

The catch is that all of that occured between Feb and June 07. I want to "milk the elite" for a little while longer by getting a Status Match, probably to a SkyTeam partner. I expect to fly about 15,000-20,000 miles again this year.

Knowing the usage patterns shown above, who is more likely to give me a status match, NW or CO (or should I be considering something else)? Since I don't fly enough to earn enough free tickets to take the entire family on vacation, my goals are less related to bonus mileage and more related to access to faster check in, upgrades, exit rows, etc. on my business trips.

As a side note, I fly from IND which is a focus city for NW, but I've enjoyed past experiences on CO better than NW (would I have a better experience on NW if I were elite?).
