When I asked if it would make a difference if I wasn't, she said yes, indicating that separate classes might mess up QR's system. I was a bit puzzled why the class I was flying on QR would be relevant but didn't say more. It was only after I had gone through security and immigration that I realized she had upgraded my SQ segment to J as well!
So not only will SQ interline, at least at some airports, but it seems it's possible to get an upgrade out of it as well...presumably at the generous discretion of the check-in personnel.

Anyone knows if SQ will be able to interline baggage from SIN all the way to ORD when the onward connection is on a different class? Also wondering if there are issues connecting to a USA bound flight given the additional security measures that came into effect late last year. Not sure if the additional security measures involving electronic devices, tighter screening etc are supposed to be done at the first port of departure or my final stopover point at NRT with the direct flight to ORD.
