China Southern--where to credit in 2019
I understand from this forum that China Southern is out of the Skyteam Alliance. I have a flight on Feb. 23 in business. Although Delta's website still lists China Southern as a partner airline for which one can earn Delta miles, I'm not sure that is correct. And I'm not seeing any evidence that the relationship with American is active yet. Assuming one cannot get Delta or American miles, as a US traveler with frequent flyer accounts in all the US based airlines, as well as BA, what would folks suggest for where to credit my upcoming flight on China Southern? In other words, where would the miles not get wasted? Thank you in advance for your thoughts.
