Both BA and AA is not operating their LHR-PHX route since mid-March 2020 ( when border restrictions started to hit ) and most likely it would be pushed again.
AA is currently flying from LHR to JFK ( x1 daily ), DFW ( x1 daily ), CLT ( x3 weekly ), and I would assume that routes like PHL & MIA which connects a significant amount of transfer pax would return before PHX, BOS, LAX, and RDU.
