I've seen several threads about this, but thought I would start another so I could put in specific flying habits in order to solicit very specific advice -- seems like that is appreciated from fellow FTers.

I am Skyteam Elite Plus as a Delta Platinum. About 3/4s of my flying is US domestic which I easily do on Delta from their NYC based hubs. I prefer flying on Delta so I'm not really interested in switching primary domestic carriers - though, these days, I'm not ruling anything out.

However, as my international flying habits grow, I'm realizing that I'm going to need to consider flying carriers other than members of Skyteam. These days I primarily fly to Europe -- lots of destinations which I do pretty easily on DL, AF, or KL - but am willing to consider others to avoid transfers, &tc. I'm also flying to South East Asia for at least two more trips this year and that is harder on ST.

So, I'm soliciting recommendations on with which program I should bank my oneworld miles. It's unlikely, though not impossible, that I will fly enough to earn status, so that is less important to me than the ability to put the miles to use. I don't know much about their program, but AA seems to be the best place to go. But I'd be interested in others' thoughts about ex-USA carriers.

Thanks to all for your advice.
