Has anyone had any luck booking open-jaw (MXP-SIN/HKG-MXP is the example I’m looking at)? As far as I can see you only see the companion fares through the special landing page - a general search doesn’t locate them even on dates where there is definitely availability. And the landing page only allows return bookings. Not completely certain I’ve understood the fare rules correctly, but from what I can generate on Matrix the fare isn’t restricted to simple return only.

Related to this, the LX promotion seems to be 2+ passengers but LH is 2 only. Is there a known way of booking 4pax on a single booking reference with LH, or is that not permitted? (Or for that matter odd numbers >2...?)
