Routes from airports with relatively small catchment areas depend on repeat business if they are to be sustained long term.
Since 2003 almost everyone in Cork who wanted to visit Prague has done so at least once . It's no longer the cheap city it was five years ago.
CSA did operate for almost 4 years but balked at going head to head with Aerlingus given that they already had indirect competition from WIZZ, Malev and Centralwings.
It might be worth asking them to come back but they recently reduced PRG DUB from 2 to 1 per day so it doesn't look as if they're in an expansionist mood at the moment.
Of course it is considered an established route so it won't qualify for incentives untill November 2009.
