I don't know if this will be useful to anyone, but I thought I'd give the heads-up that Ryanair are doing "free" flights between certain destinations, and on certain dates, atm. You need to book by Monday though.

I just booked myself returns to Dublin and Milan for £2.02 each The flight your booking needs to be at least 2 weeks away, but before 30th August, to qualify... all the terms etc are on the site.
