I was considering a trip to London from NYC via 1st class. I've attached it below, but I am confused on how I'd be able to place the trip for only 100k points. It says thru SPG, but SPG no longer is around. My options would be American Express MR points, Chase UR points, Marriott points, or Hilton points. Some how, I need to get 100k in points from one of these programs over to Korean Air or Asiana Airlines in order to book with Delta or United. I'd prefer United as I have a United Club.
Can someone please tell me how to do this step-by-step? I've never done all these transfers before as the last time I traved it was through SPGFlights and was quite easy.
Thank you.
