Thanks for the thread. I've got a transatlantic ticket to DUB booked on Avios, and I'm thinking of continuing to the UK. But I'll need a "normal" amount of luggage for this trip: rollerboard and small "additional item." It sounds like the "new" Ryanair would work for me. And, jeez, some of their fares from DUB to the UK are truly DIRT cheap. Any reason not to do it? I will check my luggage sizes and not bring a large rollerboard.
