The stats for NQY-SEN are available via the caa website. The numbers are down on last year but its a Q v a 319!
From what I understand from people who have flown the route it seems to be quite well supported but who knows what the yield was !
I would be shocked and surprised if it doesn't return, however many of the routes flown on the NQY based Q will depend if BE are awarded the tender to operate NQY-LON under the PSO contract.
