I'm somewhat astonished by the glitch in the Ryanair booking system and I try to predict what are going to be its consequences for the carrier and its passengers. Want to depart on, say, Friday? After you have selected the day from the flight calendar, the booking system puts in your basket the ticket for... the next day. If you are observant enough, you are still able to verify it before the purchase, but otherwise you end up with the flight for Saturday. Unhappy? Now, let's wait and see will FR be friendly enough to adjust your booking afterwards...
Can't believe? No, it's not just today, it started at least a week ago. Try to simulate any booking, surprise yourself.
Hmmm, hasn't happened to any of my bookings made this past week and is not happening as we speak either. I've just done three test bookings. Strange.
