Not going to go to this one at short notice but there are flights for very good value, comparatively speaking.
Change from 600 with KLM and you even get to take a day flight on the way out, which is handy for a short trip (though the 0555 departure might mean you miss a night's sleep on the way to Dublin anyway).
You seem to get a better price if you go to KLM via Google flights than if you search there directly (and a couple of quid less again if you go through booking.com or one of the other agents) ...
Rain forecast for Saturday though, so I won't bother
EDIT: Even as I was typing they seem to have gone up - but you can still go Fri-Tue via Istanbul for about the 600 mark ...
