I'm debating between worldperks, skymiles, or flying blue. Currently I am a member of Worldperks

My assessment is that it seems best to be a member of AF/KL (other) if I live in Chicago and want to fly sky team. I fly to India & Nigeria for business - 4 to 5 times a year - (my own small business - so the business class and full fare economy fares are too expensive) and KL/AF/AZ have the best fares to India plus I get 3 choices for flights with only one stop in Europe. I somehow always seem to miss platinum because 1) I have to fly oneworld or *alliance because I don't get a reservation on airline of choice, 2) I use a mileage ticket

This way I can get gold status and lounge access for only 40,000 miles.

Before skyteam - I was flying * Alliance, but I only have one flight I can use out of ORD to my destinations - LH and I can't believe that such a major European carrier does not have personal TV screens in economy

I wouldn't mind One world given that I sometimes need to stop in LHR, but I refuse to fly BA unless absolutely necessary given that they only give 25% miles on discounted tickets.

I can show addresses in the US, Nigeria, and India

Any thoughts?
