I was pricing Fr Bhd - Stn soon and the fare was £15 return. I don't think Fr are making much money at Bhd, if any, at this time.
FR regularly sell flights to London from Dublin, Cork, Shannon, Kerry, Knock and Derry for similiar money and still seem to make a profit so why should it be any different from Belfast? I think Belfast people still aren't used to Ryanair fares yet. They give you this really cheap headline fare but when you add on Credit Card fees, check in fees, baggage fees etc. etc. the prices are far higher.
