Indeed, looking at EF I can see the BA181 / 180 rotation has been zeroed out from the start of the summer schedule which 99% of the time indicates a pending cancellation of that service. Ringing BA now unfortunately won’t help because the agent can only offer you free alternatives once it is officially cancelled in the system, so hold on until you see the notification and then you will have EWR and JFK alternatives at your disposal for rebooking when the time comes.
