Slightly different from the 'Free Flights from Bristol and Bournemouth' post.
Ryanair are now doing free flights in/out of Belfast (City) airport.
They fly there from the UK from Liverpool, Stanstead, East Midlands and Glasgow (prestwick)
Hope someone can find some available dates!
Book until 5PM friday - but knowing ryanair they will extend it several times!
UPDATE - As expected, the booking deadline has been extended until Midnight monday.
UPDATE2 - Surprise surprise, ryanair have extended the offer again! Now until midnight Thursday
