It’s worth noting BA is going ‘back’ to MAN, with 32 weekly one way flights via Cityflyer to about 12 European airports and 3 ‘based’ aircraft over the weekend. Then it uses Sun Air to tap into GOT and BLL with up to 21 weekly flights and finally the Shuttles to LHR.
Yes, small fry compared to a large base, but from acorns and all that.
