My point of origin is MKE. I am not “married” to an ICN connection. I just find that ICN is great for an overnight rest after the long flight, even using Delta One.

I am also thinking of flying to IST on DL/KL/AF. Then flying on to CMB on TK or even connecting in Qatar if I can use their transit package where
you can stay in Doha for a couple of nights before continuing on.

Thank you all for your thoughtful answers. They are really helpful!
