The trip is:
DUB-LHR-HEL-JFK-LAS-LAX-JFK-HEL-LHR-DUB where DUB-LHR and LHR-DUB are BA; LHR-HEL-JFK and JFK-HEL-LHR are AY and JFK-LAS-LAX-JFK are AA
and currently JFK-LAS and LAX-JFK got cancelled and rebooked
What makes it even more interesting is that the rebooked flights have the same flight times/dates but have had their flight numbers changed from BA5051 & BA2408 to BA4679 BA4767 but despite there being no changes to the time or date I have this message in MMB: "Your new itinerary is below. You can review and accept this itinerary or find a different flight." - But I have to call and cannot review/change this online
