Be interested to know how you know this as they were on about adding a fourth
daily service next Summer from Dublin?
If you stripped out the US bound passengers on SEN DUB, you might be alarmed at the level of point to point traffic. Using Dublin SEN as a barometer to the potential of a ORK SEN might be quite flawed.
I'd also agree with your asertion;
I'm very sceptical about such a move.
BFS, WAT, and GWY to SEN didn'r work. WAT and GWY had no other London route, hence with traffic on Cork London, we can safely rule out SEN.
