This is my first post so I hope this is in the right section. I figured since I am new this was the place to be. I need some advice and thoughts. I travel all over the U.S. (and international from time to time) for work and for the past two plus years I've stuck to flying with either Delta or United. I was Gold on both all through last year but with a few months of little travel, I have been brought down to just Silver on both. I guess my question is, if I had to pick between Delta and United, which one would be better program wise? I live in Los Angeles where United is a hub but Delta is also a semi hub here as well. If you were in this dilema, which carrier would you try to stick with that gives the best perks? If I stick with one, I could probably get to 75-100,000 miles. At that range, who will give me the better perks?
