You have to fiddle the dates around a bit to arrive at the direct flights, but I'm currently finding MAN-BOS for £1,000 in Upper and MAN-SFO at a slightly less amazing, but nonetheless very good price of £1,700.
Example dates:
Sat 12th - Sat 19th August for BOS
Fri 18th - Fri 25th August for SFO
Seems to be spread across the whole summer season.
MAN-JFK currently going for £1,400 as per the currently advertised sale!
Edit: Just to add to this - if you perform the search looking for fares in the I Class bucket, the price goes up by only £300. Consider that for this you qualify for the car transfer at both ends, but also fall into the flexible ticket classes for extra TPs (200 per sector, so 400 TP total). Not for miles though strangely, but it's still a very nice earner.
