Future VA or BA upper class/business class sales?

I'm flying to Boston from LHR or BHX in September and i'm holding off from booking as prices are so high, my fallback will be Aer Lingus.
Does anyone know, if there is a likelihood of a VA or BA sale before September as an alternative to AL? Many thanks.

This appears to be a duplicate thread. Perhaps a mod would lock it?
