No inside knowledge at all.
I know how much our TA pays to fly me too and from MAN or connect me through MAN, I know not the yields involved. But it costs considerably more to fly NQY-MAN than it does to fly SEN-MAN.
All I’m saying is that I think the route will grow the liter it’s left to bed in and the more codeshares and connections it serves.
It’s a bit too soon to be writing the route off in my opinion.
Before long you will end up with CX, EK, VS, AY etc codeshares and SEN will be opened up to a vast amount of airports that currently aren’t an option, the route will grow.
