Ideological flight of fancy can only lead to a terminal form of madness

FIVE euro. That’s what it costs to land a passenger in Dublin. To put it more precisely, that, on average, is what it costs an airline to land a passenger in Dublin.

And that €5 is, of course, built into the cost of the passenger's ticket.

It's possible that, if Dublin airport was cheaper to run, the €5 could be reduced a bit. And of course, if Dublin airport was more expensive to run, the €5 could increase.
