to London tend to be significantly cheaper than such fares where the roundtrip starts in London. If you are able to book your travel significantly in advance, perhaps you could find a way to get yourself an inexpensive one-way (maybe by redeeming frequent-flyer miles?) from LON to Upstate New York, and then purchasing your subsequent roundtrip (or open-jaw) tickets with an Upstate New York origination.
It depends on when you are flying and if you meet Sat night min stay requirements on roundtrip fares. There are seasonal roundtrip PS/PE fares ex-LHR to ROC/BUF/ALB from $1300USD/1000GBP range. The currently cheapest fares you will find ex-US are currently $1800 roundtrip (which are also seasonally restricted and have a Aug 15th expiration for purchase). DL/VS/AF/KL coordinate fare filings between US and EU as part of TATL JV (it can pay to check fares on Google Flights as, while they coordinate fare filings, there can class inventory availability differences on individual flights depending on marketing carrier).
