If looking to be positive, we can remember that there was a lot of skepticism over Ryanair's initial use of secondary airports. That said, Ryanair started at Waterford an look how that went for them.
One way or another, it won't be feasible to operate to the secondary airports without a bus service being in place.
On completely different note, Cork to Zurich flights seem to start from €210 rtn (same dates from Dublin are coming in at €334 rtn).
However, if you try to feed in a long-haul connection, the prices go through the roof.
For example the return flight to Johannesburg is €3,130. Here by contrast, the price from Dublin on the same dates is €1,148.
So it looks like the pricing is to pretty much force people to use it as point-to-point only, but still allow the connection.
That's a bit disappointing for anyone hoping the route might develop into something more sustainable than a brief summer service.
I presume this is because the operating company is down as 'Swiss Global Air Lines' for the Cork flights, when all others are down as being operated by 'Swiss'.
