EGLL
No one knows what will happen with the EGLL EMBs as the winter schedule has still not been finalised! It is merely an assumption that regional will be staying in London for a little longer.
I'm guessing that the crew at the bottom of the mainline seniority list are longing for regional to stay put though, as while the EMBs remain in London there will be no mainline redundancies. With 6 airbuses to be parked up at MAN for the winter schedule it does look like mainline will be rather over-crewed.
