Welcome to Flyertalk!

I think this question will be best addressed in the American Express forum, so I'll move it there. (Arguably it would be appropriate for the Delta forum as well.)

I hope you get an informed response over there. If not, feel free to post your question in the Delta forum.

Thanks,
