surely it's better to be getting people paying the ten euro and spending money at the airport that closing at 4 o'clock .
No its about trying to maximize usage of the assets and not to lose money.
Approx 650000 passengers are expected to use Knock in 2013.
Assume 50000 are minors then that leaves 600000.
This is both directions so only 300000 are paying the €10 departure levy.
Airports are expensive to run.
Unless there is sufficient
extra traffic generated by permitting late flights then there is no economic case.
