For the months of April and May next summer:
EIN -1 weekly released at 3 weekly, then increased to 4 now showing 2
EIN was released at 2 weekly and is currently showing at 2 weekly.
Also it didn't exist at all last year - you seem to be attempting to compare this year's flights to last year so to include a new twice weekly service as a drop is bizarre to say the least.
A more balanced view of the situation in these months might be something like this:
EDI down three (a dash 8 so in terms of loads about the equivalent of down 1 737-800)
ALC down 1 weekly (if that is finalised)
GRO down 2 weekly (resumes June)
LPA down 1 weekly (resumes June)
BGY down 2 weekly (resumes June)
However, this needs to be assessed against the gains...
EIN up 2 weekly
KUN up 1 weekly (you seem to have ignored this one entirely)
London Airports up 5 weekly
So overall, possibly a slight increase in numbers in these months. Then with the resumption of services to GRO, LPA and BGY, the new service to PIK and the continuation of the other new routes (EIN and KUN) you're looking at sizable gains from June to September.
