The only extra slots BA have applied for at MAN is to increase LHR and start a new Sun Air route to Oslo.
The LHR schedule ex MAN for winter is currently showing quite significant reductions over last winters ops at the moment. This could be that the schedule is still work in progress, but at the moment, the second nightstopper that operates in winter is showing operating in only a few days of the week. Some days are showing as low as 6/day mid week as opposed to 9/day last year.
