Since BA reintroduced MLA in 2014, its always seemed to be to be a bit of an unwanted child! Yes, it clearly makes money with the daily rotation, but at random times to fit in with the rest of BA’s schedules. And some timings are really quite horrible/inconvenient. I doubt that even at peak times BA would wish to (or indeed could) add another rotation.
