Ah Poached Egg,
Why don't you travel RYR with a very generous 10kg hand luggage only, and check in online, and get automatic priority boarding?
I have travelled ex Dub to Seville, Malaga, and Biarritz this way in the past while, and it is absolutely brill! No waiting at carousels at the other end either! Might I say that the flight one way to Seville was €17.98..... and the flight to Biarritz was the same price return!! Now if I get the train to Cork from Dublin it is around €60.
Admittedly the cost of the Malaga gig was a bit more, but not too bad.
I just love the fact that on RYR one can check in online with hand luggage and sail straight through security, and no wait at the arrival. AerLingus has not yet got online checkin for Malaga, which I discovered to my cost recently. Had to queue with the mega suitcase brigade even though I only had a small hand luggage bag. It's on the way though I believe.
Checked in luggage is for long haul in my humble opinion, but no doubt some still do need to do this no matter how short the flight.
