A few somewhat related questions:

If we fly SIN to KUL on MH the day before a QR flight, do I read correctly that MH will interline our bags onto the QR flights?

If we can't get online BPs for the QR flight, is the transit desk able to issue them so that we may remain airside?

While we plan to book the airside hotel, may we visit the MH F lounge the night before with our next day QR BP? Both pax are OWE.

Finally, any tips to finding MH award space in biz for 2 pax for the SIN-KUL flight? I'm fine flying economy on the short flight, and I don't think biz is worth the current US$400 fare per pax. But if we could find biz awards, we'd be able to spend some time in the SIN QR lounge prior to the MH flight.

Thank you in advance for any insight.
