Singapore Airlines KrisFlyer - LHR Lounge Access on mixed class ticket

Hi

Have a trip next week to Sydney from LHR with SQ.

Managed to use my miles to upgrade the SIN-SYD leg of my journey to business class but not the LHR-SIN which will be in economy.

My question is will i be able to gain lounge access in LHR or just in SIN?

Any info appreciated.

Regards

If you are Kris Flyer Gold as per your signature then you have access to *G lounges regardless of class of travel (ie in LHR and SIN).

If not *G then only in SIN - as you are not departing from LHR in business class.

*G lounges plus LHR VS Clubhouse IIRC.
