Hi,
I've recently booked an award flight with US, which start with LH, then 2 segments SQ, followed by NH and finally LH again. Looking at the US website with their given PNR shows all segments and a ticket number, wrong class but that seems to be normal.

LH PNR does not show the second SQ leg on lufthansa.com, nor does it with checkmytrip using the LH pnr. There isn't any indication of a ticket number either. When I was talking with SQ callcenter I was able to do a seat reservation and given a PNR, but that seems to be pretty pointless at the moment as from what I've read you can't check award trips with the sq website atm.
Now my question is, how worried should I be about the missing leg? Whom should I contact about it?
