Actually, Dublin is more than worth a brief stopover. Why not factor in a night there, and buy the Ryanair ticket in advance online, thereby getting a good deal by booking early? It might not be such a bad idea, given that as we move into the winter season now weather can play a role in the dependability of trans Atlantic flights.

Or, when you arrive, buy the ticket on your smartphone and check in online. The price might be more than an overnight stop, though. Or check what another carrier has to offer, for a later flight that day (e.g. KL, EI), leaving enough time for potential delays.
