AQo, standard yes?

Saturday night, everyone on Party is drunk. I am just double checking to make sure this is standard.

I am dealt AQo with Qs UTG+1.

Preflop: UTG limps, I raise, two callers, BB calls.
Standard.

Flop: As Q xs
BB leads, UTG calls, I call, rest fold.
Anyone raise here?

Turn: Ks
BB leads, UTG calls, I raise...
I have the nut flush redraw but I'm not sure if BB may have been leading a flush draw on the flop. Do I raise anyways?
