Well my BA1394 flight tomorrow (8th) is now asking me whether i want to refund or rebook which I'd love to do, but my flight from LAX->LHR today is still showing as scheduled even though the aircraft is still at LHR having been delayed for 6+hrs so I guess my flight will be delayed/cancelled...
Edit: Apparently the outbound flight did leave roughly on time, its just flightradar not being updated:

but this shows it enroute:
