Not done one of these for a while, but just booked:

LHR JFK return, out 1805 Jun 7th back 1830 Jun 9th, £275

5000 avios for £100 discount, 8650 avios back, net 3650 (GCH)

Net cash price £175

Same flights available via travelup £252, double price promise returns £50, claim already settled.

So overall net is £125 less the avios, say £35,

final net total £90 (may vary). Lots of other dates and time combos also work. But anyone who cares to join me on this one is welcome. A generous 40 TP too.

Very good deal this 5000/£100. Shanghai looks good in May in Y, and wife and boy off to see the Grandparents in Kul for peanuts (in the sense of not costing much, though there will certainly be real peanuts too) If you can combine with a price promise deal it's fantastic.
