Hi

I have been reading a lot on the forum to try and answer a relatively simple question: for business reason i am going to have to fly at least 8-10 times to the USA from Israel next year and need to decide whether to go DL or CO (I will fly both via ATL and NY anyway). El Al is not a consideration as i prefer to fly on weekends. The main criteria is how fast one can earn status and how easy it is to redeem miles on non domestic routes. I found a lot of contrasting opinions (most people criticizing their own program: I guess the neighbor's grass is always greener). Any kind soul willing to put in their wise penny?

Thanks
