It will continue
Of course its possible...
And logic tells us that the numbers will be worse for at least the next 5 months (barring any weather anomolies or new route announcements).
For November - March, we'll see one less 737 a week (Egypt) versus the same period last year and no Southampton operations. That can only translate into a further YoY decline in passenger numbers.
November/December may yet be a little more tricky to predict given the snow during that period last year and the lack of it so far this....but in good weather terms...its downhill for at least 5 months.
Whats more, if there are no new routes come the Spring, the decline YoY will continue as next spring/summer we'll lose Southampton and Turkey flights versus last year....in short until new routes come online the downard trend in passengers will continue until around August next year is my guess (which is when the Turkey flights stopped (I think?))....
None of this should be a surprise to anyone unfortunately....
