Will you have luggage? On one PNR? Some airlines are refusing to interline bags when on separate tickets and that could complicate your trip. Not sure if this applies to AA<>LY but something to bear in mind.
I will have luggage. The flight will sold as a AA flight on LY metal. There won't be any problem with interline.
I just don't want to stress the whole flight into lhr wondering if my connection was too tight... ☺
