Turkish Airlines Miles&Smiles - TK hand-off to UA on seperate Itin?

I'm flying TK from IST to LOS, then I have a separate itin from LOS to IAH on UA. Is it possible to have TK print my boarding passes for my UA flight in IST?:confused:

There is a thread about connecting in Lagos in the UA forum..... Scary. TK would not be able to print boarding passes regardless.

Consider your self lucky if TK tag your bags all the way to IAH. Printing BP for LOS-IAH is out of the question; not even possible for TK to do this.

I would choose a better (and more civilised) place to change flights...I suggest FRA
