BA Cityflyer crews are not part of the strike action. So all flights from LCY will be operating.
As dhc83driver already gave a list of destinations BA Cityflyer operate to from LCY I will not repeat them, however he missed out our winter ski destination of GVA (Geneva) not sure when it's starting though, but it will be in time for Christmas.
As for the LCY-JFK route: this is crewed from Gatwick, as far as I'm aware Gatwick flights for the most part should not be affected as much, as crews there are already on different contracts to those at LHR. So it seems that the LCY-JFK should be running. Not sure who to ask for a definate answer though.
Hope this is of some help to you.
