The easiest way to think of it is taking connecting flights.
So, if you want to take a return flight from Cork to Riga, a flight that leaves Cork for Prague in the morning and one that comes back in the evening gives you the maximum possibility for connnections in Prague.
The Aer Lingus Cork-Prague flights don't arrive until around 8 pm, which is far too late to connect on from Prague.
Also, not all airlines allow it e.g. Ryanair and BMIBaby don't
Currently, the connecting traffic from Cork tends to use Heathrow, Amsterdam, Paris, Prague or Budapest
