Well, that win exploded, thanks to the LH strike.
LH declined to rebook us (there was F available on LX, BA, and AF that would have worked), saying it was UA's award ticket and they couldn't rebook it. Not convinced, but after 2 hours on the phone had to give up.
UA - lucked out with a fabulous agent who opened up IN space at a remarkably low rate to take us via LAX & ZRH. 2 windows in LH F have turned into 2 middles in LX C, but at least we're getting there. Unless the SFO weather messes things up of course.
