I used to travel double what I do now and
I had been an elite (Gold) on NW and then when they become DL for a year or two after. I didnt switch over to AS but had status on both. Now I bank everything with AS. If I decide to go elsewhere, its going to be UA to give them a try. What level of elite status on AS are you? If you are MVP/silver level then Id try to stick with AS. At DL theres not much difference between general passenger and silver. If you would be a DL gold equivelent then you are possibly one step above pond scum but still not really treated that well. If you are flying enough to make Platinum or higher then by all means try DL. As far as AA goes....I wouldnt touch that with a ....39 and a half foot pole. I believe DL will match you to silver or gold accordingly but like AS the very top tiers you have to earn


All just my opinion
