As a regular for me, I don’t recall this service. So it may be a switch or rejig for summer 19. I know the LGW fall between 9.35am ish and then 4pm ish. So this could be an additional slot or a replacement slot for another. But yea it sounds like a new time for LGW.

A vague recollection could be that this was mentioned on Headforpoints. Worth a google. But I’d book it. I can’t see the AGP flights taking any hits for BA since Monarch went under.
