Hi Guys,

I apologize first if I posted it on the wrong forum (wasn't sure if it should be on OneWorld or the Singapore section).
I will be flying QR944 arriving in SIn at 20:15, connecting to CX714 a few hours later (1:20 the next morning).

I understand that QR uses Terminal 1 and CX T4. But since SIN mixes both arrival and departure movements, is it possible for me to use QF/BA lounge before heading to the remote T4? Would QR and BA admits me? (Business Class ticket both legs without OW status)

What if my next flight is not CX714 but a daytime flight the next day? Can I still visit QF/BA lounges for a while, then leave the airport (assuming I will have no checked bags to claim at SIN)?
