As a point of interest, the BA website home page has strike information which when followed through to individual flights shows the wet lease carriers for flights.
eg. DUS-LHR Saturday 20th March
BA935 Operated by BA Airbus
BA937 Operated by Titan B757
BA939 Operated by Transavia B737
It looks to me as if a pretty robust schedule is taking shape.
It is there for all to see, of course for the PAX, but striking CC I suggest you take a peep.
